DeeSubquestion

What kinds of distances are there in geography?

1

Use Source 1 in your coursebook and the Geo Guide.

a What is the name of the chapter in the Geo Guide that includes G51 Elevation zones?

b What mountain range do you see in Figure 2.12 of the

Geo Guide?

c Write down the definition of relief as mentioned in G110

Relief of the Geo Guide.

d How many different relief types are there?

e What type of relief is the mountain range in Figure 2.12 of the Geo Guide? Explain your answer.

Read Source 4 in your coursebook and use G110 Relief in the Geo Guide.

Find the correct map of Iran in the atlas. a What type of relief does the Alborz mountain range have?

b The highest mountain range in the world is also shown on this map ( Alcarta: 154A). Which mountain range is this?

c On the border between Iran and which other country can you see lowland?

2

Use Source 4 in your coursebook.

a At what elevation does the route from Tehran to Chalus start?

b Draw this route in W15. The vertical axis shows the elevation of the route in m; the horizontal axis shows the distance in km.

Chalus is already in the right location in W15. Chalus is 0 m above sea level.

Write the name Tehran at the correct place in W15. c Draw the elevation profile of the route using the map in

Source 4. This is how you do that: - The elevation of the route from the starting point up to 20 km has already been drawn on the chart. - Look up what the elevation of the route is after 30 km using the map in Source 4. Put a dot at this point. - Do the same at 40 km, 50 km and so on until you reach Chalus. - Connect all the dots by drawing a line and this will give you the elevation profile of the route. d What is the highest point of the route?

e After how many kilometres is this highest point of the route reached?

4

Use Sources 2, 4, 5 and 6 in your coursebook. Read the triangle in G51 Elevation zones in the Geo Guide.

a Check Figure 2.12 in the Geo Guide to see at what heights the various elevation zones occur. Colour in the elevation zones in W15. Choose the colours yourself. Also colour in the legend. b Through what type of vegetation does the route mainly pass?

c Which Source in this section fits this part of the route?

d At what elevation do trees no longer grow in Figure 2.12 in the Geo Guide?

e Above what elevation, according to Figure 2.12 in the Geo

Guide, is the tourist in Source 6 cycling? Explain your answer.

5

Use Source 3 in your coursebook. Read G51 Elevation zones and G52 Elevation and temperature in the Geo Guide.

a Fill in. If you climb 1,000 m up a mountain, it gets

°C colder.

b How much colder will it get if you climb 3,500 m? °C

c Using G51 and G52, explain why there is perpetual snow on the peaks of the Alborz mountain range.

d Why are the temperature differences in the area around

Tehran so much larger than in the area around a Dutch city?

a Use Source 7. Which line represents the absolute distance?

6

Use Sources 6 and 7 in your coursebook.

b Indicate for each of the following whether the relative distance increases or decreases: - Road 59 is always busy at the start of the holiday period. a Make correct sentences using the following words: - relative distance – cyclist – relief

- perpetual snow – elevation zone – high mountain range

b Complete W16 using G110 Relief and the Midden-Oosten en Zuidoost-Azië (Midden-Oosten - Overzicht) map in the atlas. Enter the correct name in the third column.

Kies uit: Zagros Mountains – Ahvaz – Zabol – Yazd.

high mountain range

- The road conditions on the highest part of the route are poor due to snowfall.

- The government wants to build tunnels on the route.

- The cyclist in Source 6 decides not to take a break and to keep going.

c What could cause the relative distance on a route that you sometimes take to increase?

a Work out the absolute distance between Tehran and Dubai

in Source 8. Write it down.

b Why is the difference between the absolute distance and the distance by road to Dubai so big?

c Using Source 8, think of another reason why the route from

Tehran to Dubai can take very long.
