About This Book Introduction Volcanoes and earthquakes can change the surface of the earth very suddenly, and without warning. They both involve the release of a huge amount of pressure from deep within the earth. A tsunami, or giant wave, can result from an earthquake or volcanic eruption. The devastation caused by earthquakes, volcanoes and tsunamis kills many thousands of people every decade and destroys homes and land, but there are also many benefits of these powerful phenomenon.

r o e t s Bo r e p ok In this book you will find ... u S Teac he r

The study of volcanoes, earthquakes and tsunamis provides the basis for an interesting, exciting and motivating classroom theme, for students of all ages.

Making an erupting volcano Time: One Term 1. Make a volcano shape by moulding chicken wire and fastening it with masking tape onto a big piece of card. In the centre place a plastic bottle sitting on an upturned ice cream container. 2. Cover with papier mache and paint. 3. Spray with a coat of lacquer (spray can is easiest). 4. If you desire you can place a forest, rivers, villages or farms around the base of your volcano. 5. To erupt the volcano, use a funnel and pour a cup of bicarbonate of soda into the plastic bottle. Add a cup of vinegar that has been coloured red with food dye. The eruption is very quick so make sure your class is seated around the volcano when you do this. Note: The activity is best done outside.

1. Make a small hole in a shoebox and pass a piece of plastic tubing about 1 cm in diameter through it. 2. Place a balloon at the end of the tubing inside the box. It is easier to blow the balloon up partially (to about 12 cm) before placing in the box. Keep your thumb over the other end of the tubing so that the balloon doesn’t deflate. 3. Cover the balloon with flour and flatten to make a smooth surface. 4. As you remove your thumb, the balloon will deflate, causing a crater to form in the flour just as a real one forms when magma leaves a chamber.

Demonstrating how and why magma moves inside volcanoes 1. Make up a lemon jelly (or you may use gelatine). 2. Using warm water to loosen the jelly, turn it out onto a piece of pegboard (which has holes underneath). 3. Using a syringe, slowly inject red food colouring into the jelly, through a hole underneath. (Remove any air bubbles first by ejecting a small amount of dye.) The dye simulates the lava forcing its way through the earth.

The release of pressure has allowed some bubbles to appear and grow in size. 4. Now shake the bottle well. This will force the gas out of the soft drink. Unscrew the lid and watch the ‘lava’ erupt. As the pressure is released, the gas forces the soft drink out of the bottle. Page 8

About ... Volcanoes, Earthquakes and Tsunamis Volcanoes

A volcano is a vent or chimney that provides an opening in the earth’s surface through which molten rock called magma, can escape. This is often accompanied by gas, ash and pieces of rock. The shape of a volcano is made up of layers of hardened lava and ash that build up with each eruption.

r o e t s Bo r e p ok u S

Volcanoes come in different shapes and sizes, due to the rate of flow of the lava. Slow moving lava that travels a long way will produce a gently sloping, shield volcano. However, lava that hardens before it can flow very far builds up high layers, like Mount Fuji, in Japan.

Teac he r

ew i ev Pr

There are several different types of eruptions. These can cause huge devastation to a landscape, destroy farmland and may lead to loss of life. Lava pouring into the ocean can cause beaches to disappear and new coastlines to form. Volcanoes however, do have a positive side. Lava breaking down over the years can provide areas with rich, fertile volcanic soil. Volcanic rock may also contain precious stones such as diamonds and opals. Hot springs are a source of geo-thermal energy.

Earthquakes

When brittle rocks beneath the surface of the earth break suddenly due to pressures deep within, an earthquake can occur. This pressure often takes hundreds of years to build.

© ReadyEdPubl i cat i ons Whatever the cause, earthquakes can result in huge devastation and damage. An impending earthquake • givesf no warning and create o rr e vcan i e w chaos. pur posesonl y• Earthquakes can also be caused by the collision of tectonic plates.

Tsunamis

m . u

Each year about 500 000 earthquakes occur around the world. Most of these tremors are very small and many occur far out at sea.

w ww

Tsunamis are giant waves that are caused by an earthquake. They can reach heights of 30 metres and can travel at speeds of up to 800 kilometres per hour.

. te

They can cause massive devastation when they suddenly crash down upon the coastline.

o c . che e r o t r s super

Many places, including Hawaii and Japan, have sirens at the ready to warn the population of an approaching tsunami. When a warning is given, people must move as quickly as possible to higher ground.

Inside the earth

The earth is more than 12 000 kilometres thick. The outer layer of the earth is known as the crust. Under the crust is an intensely hot layer of dense rock called the mantle. Inside this mantle lies the core, which is made up of an outer layer of liquid metal and a dense inner core of solid metal alloys. The temperature in the core may be as high as 5000oC. Heating and cooling that occurs in the core causes the magma from the mantle to rise near the surface of the earth. When it does force its way to the surface, it can cause earthquakes and form volcanoes.

Page 10

Ready-Ed Publications

Teachers’ Notes When a volcano erupts Magma from deep inside the earth’s mantle rises to the surface and collects in a magma chamber where it mixes with gases and water. Pressure builds up and forces its way though a weak spot in the earth’s crust. When this pressure pack of magma finds a vent or chimney, it surges up releasing red-hot lava, steam, gases and ash through the crater at the top of the vent.

Drifting plates

r o e t s Bo r e p ok u S

ew i ev Pr

Teac he r

The earth’s crust is made up of about 15 huge plates that actually float on the mantle. These fit together like a jigsaw puzzle. Over millions of years these plates have slowly drifted due to movement deep within the earth. This is known as the continental drift. The theory of plate movement is called plate tectonics. Most volcanic activity occurs along the edges of these plates.

Scientists believe that 200 million years ago land on the earth was all joined together forming one solid mass. These masses of land broke up over millions of years to form the continents as we know them today.

Volcanoes under the sea

Underneath the ocean, the crust of the earth is about 5 km thick - much thinner than the continental crust which may be up to 60 km thick. Many volcanoes occur under the sea and will eventually break through to the surface. Examples of this are Surtsey and the Hawaiian Islands. After breaking through to the surface, and after thousands of years, an atoll may remain. This is a ring of coral around the edge of an extinct volcano that is made up of the skeletons of millions of tiny sea creatures. Ready-Ed Publications

Teachers’ Notes

‘Hot Spot’ Volcanoes Surtsey - An Island Grows In November, 1963, a huge column of smoke and ash was seen to rise out of the ocean south west of Iceland. Witnesses thought a ship was on fire. The next day a new island appeared and kept growing. The island was named Surtsey and today it measures 2.6 square kilometres. Surtsey’s birth began when two plates on the floor of the Atlantic Ocean moved apart causing a volcanic eruption. When the top of the volcano rose above the surface of the sea, lava and ash exploded out of the vent, creating a new island. This continued for several months and then a second vent appeared. After four years the island had grown to 570 feet above sea level.

r o e t s Bo r e p ok u S

Teac he r

Seeds soon reached Surtsey, carried by the wind or by birds. They produced flowers and grasses. Soon, sea birds began nesting among the rocks. By 1980 there was a whole breeding colony on the island.

Hawaii

ew i ev Pr

Volcanic islands often form over very hot spots in the earth’s mantle. The Hawaiian Islands were formed in this way, by ‘hot spots’ under the Pacific Plate.

A hot spot volcano occurs in the middle of a plate. The plate slowly moves over a magma source that erupts, causing a chain of islands. A good example is the Hawaiian Islands. Kauai was formed first, then Oahu, Maui, and Hawaii. There is a new island named Loihi, currently over 3000 metres high, that is still more than 1000 metres below sea level. Scientists estimate that in about 10 000 years Loihi will break the surface.

© ReadyEdPubl i cat i ons The biggest and youngest island, Hawaii, isp made upp of o five s volcanoes. When ity eventually moves • f o r r e v i e w u r e s o n l • off the ‘hot spot’ it will landslide into several smaller islands. The Hawaiian ‘hot spot’ has been active for 80 million years. All of these volcanoes are shield volcanoes.

Vog is the term given to volcanic air pollution and is a problem in Hawaii. Kilauea volcano emits sulphur dioxide gas and other pollutants that react with oxygen and moisture in the air. This produces vog and acid rain. Vog is a health hazard to people with pre-existing respiratory ailments. Acid rain damages crops and can leak lead into household water supplies.

Kilauea volcano is the largest active volcano in the world and currently gives spectacular views of lava pouring into the sea, lava skylights dotted along the hillside and other sights depending on the temperament of the volcano. The eruptions of Kilauea have resulted in 505 acres of new land being added to the island of Hawaii, but has caused losses totalling $61 million.

Teachers’ Notes

Different Types of Volcanoes Shield Volcano: These are made up of basalt-rich lava which is thin and runny and spreads a long way from the vent. This results in a shield volcano which is very large with gentle, sloping sides, e.g. Mauna Loa in Hawaii.

r o e t s Bo r e p ok u S

ew i ev Pr

Teac he r

Cinder Cone Volcano: These occur where an explosive eruption shoots tiny but solid fragments of ash and rock from the volcano’s vent. This eventually builds up to form a volcano that is steep-sided but not very tall, e.g. Paricutin in Mexico.

w ww

. te

m . u

Acid Lava Cone Volcano: This is made up of lava which is very thick or viscous. As it slowly flows it begins to harden quite close to the vent, forming a cone shape with very steep sides, e.g. Mount Ngauruhoe in New Zealand.

o c . che e r o t r s super

Stratovolcano: These make up over 60% of the volcanoes on the Earth. These are quite tall and caused by a cycle of quiet eruptions of runny lava followed by explosive eruptions of thick lava, e.g. Fuji in Japan.

Teachers’ Notes

Volcanic Rocks As volcanoes erupt in different ways, lava that is released flows in different ways too. Volcanic rocks can be pyroclastic or non-pyroclastic. The term pyroclastic comes from the Greek, pyro, meaning fire and clast, meaning broken. An example of non-pyroclastic rock is the three types of lava explained in detail below. An example of a pyroclast is the rocks produced during a spectacular lava fountain. These chunks of lava and rock are thrown out forming lava bombs and blocks. Small glassy fragments can also fall to the ground during an eruption. These fragments are known as cinder.

r o e t s Bo r e p ok u S

Ash deposits can be so hot when they settle that they can weld together to form solid rocks.

The faster that lava cools, the glassier its appearance.

ew i ev Pr

Teac he r

When lava cools and hardens, it forms rock. These rocks are known as igneous rocks. The most common igneous rock is basalt that makes up most of the solid surface of the earth. Andesite and rhyolite are found in more acid volcanoes. Volcanic rocks can provide a source of minerals such as silicon, zinc, lead and copper. Some precious stones such as diamonds and opals are also concentrated in volcanic rock. Volcanic rocks such as granite, are used as building materials and pumice is used by people to scrub their skin.

Teachers’ Notes

Volcanic Hazards Primary hazards Ash and Dust: A volcanic explosion causes old lava to be blasted into small pieces and hurled through the air with ash and dust. This cloud can reach several kilometres in height. Also, molten lava solidifies as it moves through the air forming ribbons of lava and lava bombs - some measuring up to 25 centimetres or more across. These airborne fragments are called tephra. Heavy tephra falls can cause damage to buildings and cause collapsed roofs. The ash and dust can remain in the air for a long time, clogging up machinery and causing difficulties in breathing, e.g. Vesuvius, in AD 79, erupted and covered the Roman city of Pompeii in 6 metres of ash.

r o e t s Bo r e p ok u S

Hot ash can also flow down the sides of a volcano, burning everything in its path. This is known as a nuee ardente.

Teac he r

ew i ev Pr

Lava: Lava flows have been known to kill people, e.g. the eruption of Mount Nyiragongo in Zaire, Africa. The lava from this volcano travelled at speeds of 30 kilometres per hour. However, lava usually moves very slowly, allowing people to escape. Volcanic Gases: Huge amounts of gases such as sulphur and carbon dioxide are released into the atmosphere when a volcano erupts.

Secondary hazards

Lahars: This occurs when ash and dust moves down the sides of a volcano, mixing with water to form a mudflow. Lahars can travel up to 50 kilometres per hour causing huge devastation as they travel downstream.

© ReadyEdPubl i cat i ons •f orr evi ew pur posesonl y• Tsunamis: Some large eruptions can cause huge waves to generate, which travel at great speeds. Landslides and Debris Avalanches: Small earthquakes often follow a volcanic eruption and these can cause landslides or avalanches, e.g. Mount St Helens, USA - one side of this volcano collapsed in 1980.

w ww

Other hazards

m . u

These can also be caused by underwater eruptions releasing gases, e.g. the Krakatoa eruption in Indonesia (1883) caused a huge tsunami with 30 metre high waves to form, drowning more than 35 000 people.

Aircraft flying near an eruption may be faced with problems as ash may cause the engines to clog up, as happened to a KLM jet in 1990, after Redoubt Volcano in Alaska erupted. All four engines were stopped but were restarted when the plane had flown through the ash cloud.

Teachers’ Notes

Hot Springs and Geysers Bubbling hot springs are caused when magma heats water under the ground. The water may reach temperatures of up to 150oC. This water contains many dissolved minerals. When this water gushes out of the ground it is known as a geyser. Geysers are found in New Zealand, Iceland and the USA. For example, Old Faithful in Yellowstone National Park erupts every hour. Water and steam gushes out, reaching heights of up to 46 metres. This USA national park contains over 10 000 active hot springs.

r o e t s Bo r e p ok u S

Geysers eventually die as their feeder channels become blocked with mineral deposits, or earthquake movements cause them to collapse. An earthquake can also create new geysers.

Fumaroles

Teac he r

ew i ev Pr

These are holes in the ground through which volcanic gases and water vapour can escape. It is a way for a volcano to ‘let off steam’.

The gases released can give vulcanologists important information about the proportions of gases in the magma.

Mud pots

Due to the many geysers near Lake Rotorua in New Zealand, leaking steam causes pools of boiling mud in the area. These pools bubble and plop and are known as mud pots. The mud from these pools is used for a variety of purposes, such as cosmetics.

Benefits Of Volcanoes Lava More than 350 million people all around the world live on or near an active volcano. This is mainly because volcanic activity does reap some benefits. Over many thousands of years lava breaks down into very fertile soil, providing an ideal area for farming. For example, the sugar and pineapple plantations in Hawaii are built on volcanic soil. Olives, vines, nuts and citrus fruits are grown plentifully near Mt Vesuvius in Naples, Italy, and rice is grown plentifully on the volcanic earth of Luzon in the Philippines.

ew i ev Pr

Teac he r

This also breaks down over the years to provide nutrients for the soil, when it mixes with a water source.

Magma, underneath rocks near the surface of the earth, will heat water to the point of forming steam which can be converted into geothermal energy and then into electricity. Holes are drilled into volcanic rock to release the hot water held in the cracks. When the hot water reaches the surface, the steam is used to turn turbines and make electricity. In some plants, cold water is pumped down into the volcanic rock, to be heated by the magma. This method produces very little pollution and is used in Italy, Japan, Indonesia, New Zealand and the Philippines.

In Iceland, geothermal energy is used to provide hot water and heating. It is also used to heat greenhouses so that fruit and vegetables may be grown all year round.

stones such as diamonds and opals are also concentrated in volcanic rock.

Steam vents

m . u

Volcanic rocks such as granite, are used as building materials and pumice is used by people to scrub their skin.

In some countries the plentiful sulphur deposits left at the openings of active steam vents or fumaroles, is mined. This can be an extremely dangerous job as dangerous sulphur fumes are constantly breathed in, and temperatures are extremely high.

Myths and Legends

Many myths and legends came about as people tried to make sense of their changing and often violent world. They provided understanding and reasons for the eruptions and earthquakes that occurred in these ancient times, before scientific developments could discover the real reasons. Some of these myths and legends are still believed by many people today.

Volcanoes

r o e t s Bo r e p ok u S

The ancient Hawaiians believed in Pelé, the Goddess of Fire, that lived in the Kilauea volcano. She originally settled in Hawaii after moving from Tahiti. It was believed that the volcano erupted when she was angry. Many sacrifices were made to appease Pelé, and even today, ceremonies are held once a year in which offerings are made to Pelé by the people of Hawaii.

Teac he r

Steam that pours out of many vents and fissures on Kilauea is considered to be Pelé’s breath.

ew i ev Pr

Teardrop-shaped pieces of black volcanic glass are known as Pelé’s tears, and golden, hair-like fragments that are found clustered in rock crevices are known as Pelé’s hair.

Many Hawaiians today still believe in Pelé and will sweep and tidy their homes when being evacuated due to an eruption of the Kilauea volcano, so as not to offend Pelé when she passes through. The words ‘volcano’ and ‘vulcanologist’ are derived from the name of the Roman god of fire, Vulcan.

The Greeks believed that the god Hephaistos had his blacksmiths’ workshops underneath volcanoes.

Teachers’ Notes

About Australia How was Australia formed? During prehistoric times, Australia was joined to other continents. This super continent was known as Gondwana. At this time the surface of Australia was mainly covered by lakes, streams and cool rainforests. The trees were not eucalypts or wattles but pines and beech. Whilst Australia was joined to other continents, the plants and animals were very similar.

r o e t s Bo r e p ok u S

ew i ev Pr

Teac he r

Living things could move from one continent to another because they were so close. About 200 million years ago continental drift tore Australia away from the other continents and moved it further south. A sea began to form and widen between Australia and the other continents, separating them. Australia became an island continent with its own unique plants and animals. Only swimming or flying Australian animals could migrate into other lands.

Teachers’ Notes

Earthquakes: How They Occur Earthquakes send vibrations through the earth in much the same way as the ripples formed when a pebble is dropped into a pond. An earthquake occurs when rigid and brittle rocks near the earth’s surface break suddenly. Vibrations known as seismic waves, spread out from the point of fracture, known as the focus. These shock waves spread upwards as well as outwards. On the surface of the earth, directly above where the earthquake has occurred, is the epicentre. This is where the greatest damage occurs.

r o e t s Bo r e p ok u S

The line along which the break occurs is called the fracture zone or fault. The break begins at a point and then runs along the fracture zone. This is called a rupture. When the ground cracks, breaks up and then relaxes again, buildings collapse, gas and water mains fracture, flooding occurs as rivers and lakes overflow and tsunamis (giant waves) may form at sea.

ew i ev Pr

Teac he r

Some earthquakes only last a few minutes but others will have aftershocks that will occur for days or weeks afterwards. Scientists estimate that about a million earthquakes occur every year.

Monitoring Earthquakes Seismometers measure vibrations in the earth’s crust as before an earthquake small tremors may occur known as a foreshocks. These can give warning of an ensuing earthquake. A seismometer is a very sensitive instrument and measures all the tremors on the earth’s surface. It will measure or record any slight tremor or strain of rocks in the ground at a specific location. These movements can range in size from a metre or so, over a period of 12 hours in response to the gravitational pull of the moon, to motions of only a few millimeters over a period of seconds, as during an earthquake or explosion.

A seismometer is connected to a seismograph which then shows the recordings as a graph.

As an earthquake wave moves from A to B (as in the diagram below), it also moves up and down. This causes cracks to appear in the surface (as it moves upwards) and then a collapse in the surface as the wave passes by.

Earthquake Damage

Most damage occurs to buildings made of stone. Leaking gas and oil caused by an earthquake will often lead to fires which will exacerbate the damage. The Lisbon earthquake of 1755 caused huge damage to the city, started fires and resulted in huge tsunamis. About 60 000 people were killed. It has been calculated that the Mexico earthquake of 1985, was equal to 1000 atomic bombs as large as the one that destroyed Hiroshima in 1945. (Continued next page ...) Page 42

Earthquake Damage (cont.) The San Francisco earthquake of 1989 caused damage to over a million square kilometres of land. The damage to buildings and roads was estimated to be in excess of $6000 million dollars. 63 people were killed and 4000 injured. In 1995, a Japanese earthquake in Kobe killed over 5000 people and injured 25 000 others. This was caused by a fault that had not moved for 1000 years and was thought to be safe.

Earthquake Rescue

r o e t s Bo r e p ok u S Preparing For Earthquakes

Around the world various measures have been put in place in preparation for earthquakes. Children in Japan practise earthquake drills, just as we may have a fire drill. There are trained disaster teams ready to commence work in an emergency, and supplies of food and blankets are held in readiness. The streets in San Francisco, USA, have been widened to help prevent the spread of fire and also to allow emergency teams to have space between the rubble for easier access when rescuing people.

Both the Alaskan earthquake of 1964 and the Chilean earthquake of 1960 registered 8.9 on the Richter Scale. This is the highest reading ever recorded. A 7 is considered to be a major earthquake. The Newcastle earthquake of 1989 registered 5.6. The people of Newcastle weren’t prepared for the earthquake that struck them on 28th December, 1989. Collapsing walls caused most of the twelve deaths. The Mercalli Scale uses a scale from 1 to 12. This was invented in 1902 and modified in 1931, so that it can apply to damage in modern cities. One of the biggest dangers of earthquakes in Australia is that people don’t expect them to happen. Western Australia’s Meckering earthquake, 1968, was powerful enough to move railway lines sideways, break apart roads and lift the ground up to three metres in some places.

Teachers’ Notes

Predicting Eruptions and Earthquakes Many changes will occur in a volcano, often just before it erupts. Volcanoes are monitored constantly and carefully. There are observatories built close to important volcanoes around the world for this purpose. Many areas have emergency strategies in place. For example, Naples in the south of Italy, has a practice evacuation of the town every six months, in case of a volcanic eruption of Mount Vesuvius.

Minor earthquakes

r o e t s Bo r e p ok u Gases in the airS Teac he r

The rock under the volcano is forced apart by magma filling the area. Seismometers are the sensitive machines used to measure the vibrations that these earth tremors cause. Scientists can work out where earthquakes are occurring and how close the magma is to the surface.

The volcano changes shape

ew i ev Pr

As magma rises up to the surface, gases are released into the air. These levels of carbon dioxide, sulphur dioxide and hydrochloric acid may increase before an eruption.

As magma fills the chambers within a volcano the sides will begin to swell. This is measured with an instrument known as a tiltmeter. Lasers are also sometimes used.

Water temperature

The temperature of the water in crater lakes may increase substantially before an eruption, as the magma comes closer to the surface.

Teachers’ Notes

Tsunamis The word ‘tsunami’ comes from the Japanese, meaning ‘harbour’ and ‘wave’. Many tsunamis have struck the Japanese coast. A tsunami must not be confused with tidal waves as it has nothing to do with tides. Tidal waves are produced by the gravitational attraction of the sun and the moon on the oceans. A tsunami is usually part of a series of smaller waves that are caused by earthquakes, underwater volcanic activity or underwater landslides. It can travel across the oceans at speeds of up to 800 kph and reach heights of 30 metres. The height a tsunami has reached is known as the run-up and is determined by the height of seaweed found in trees on the land.

r o e t s Bo r e p ok u S

Tsunamis affecting Hawaii can originate from as far away as Alaska, Japan or South America.

An earthquake causes the sea bed to rise, resulting in a tsunami.

ew i ev Pr

Teac he r

Generally, in the ocean, tsunamis are only a metre high, and there may be more than 100 kilometres between each wave. As these waves come towards land where there are shelving beaches and narrow inlets of land, the water towers into a huge wave.

. te

Tsunami safety rules (Hawaii)

m . u

w ww

Some signs of an approaching tsunami might be the disappearance of water which exposes the ocean floor and reefs, the disappearance of reefs or parts of islands due to flooding by the tsunami, or the sight of a large wave approaching the shoreline.

o c . che e r o t r s super

* A tsunami can move faster than a person can run. * Never stay to watch a tsunami. * In tsunami prone areas a siren will sound to warn you. * If you feel the earth shake, move to higher ground - a tsunami may be on its way.

Historic tsunamis

The 1883 eruption of Krakatoa, Indonesia caused a massive tsunami. The waves killed over 36 000 people living on Sumatra and Java. In 1892 a tsunami struck Japan, sweeping away about 10 000 houses and killing some 27 000 people. The Alaskan earthquake of 1964 caused huge tsunamis. Huge ships were swept ashore. In 1975 a large earthquake shook Hawaii causing a giant tsunami that washed people, trees and rocks into a crack 6 metres deep. This was followed by a second wave that was about 15 metres high and travelled inland for nearly 100 metres. Some people died and there was great damage caused. In 1994 the islands of Indonesia were hit by a series of tsunamis that swamped fields and villages.

Teac he r

Jack lived in Hawaii. He loved the beach. He liked to feel the sand in between his toes and he loved swimming in the sea. He looked over at his sister, Lucy, who was building a huge sandcastle. A cool wind blew softly. Suddenly he heard the loud wail of a siren and lots of people began yelling, “Run, run!” He looked up and there, in the distance, was a giant wave moving towards the shore. It was a tsunami and Jack knew what he had to do. He grabbed his sister’s hand and ran and ran. He could see the big hill just ahead and he knew that they would only be safe if they reached the top. They came closer and soon they were running as fast as they could, up to the top of the big hill. It was very hard work and he was so puffed out. His sister began to cry, but he knew they were safe when they © ReadyEdPubl i cat i ons reached the top at last. f or evi e wp ur p ses on l y• “Crash!”• The big r wave washed onto theo shore, right over the beach that they had been playing on.
