Water Cycle ď‚—

First the water of the rivers evaporate into the air and condenses in clouds. Then there are precipitations, and the water goes back into the rivers.

This process happens again and again.

Acid Rain ď‚—

The acid rain is formed in the process of the water cycle. First the water evaporate and the smoke of the factories mix with the water vapour and so when it rains, the rain is acid.

This causes living things in the water to die

Types of water •

There are diferert types of water: Fresh Water: We can find it in rivers, streams and underground. We can drink it.

• Frozen Water: We can find it in the Polar Regions.We can't drink it.

• Salt Water: We can find it in oceans and seas. We can't drink it.

Pollutants Home owners:: They use chemicals, pesticides, weed killers and fertilizers on their crops. That contaminates water and air.

• Farmers: They

use chemicals, pesticides, weed killers and fertilizers on their lands and they pollute the air and the water.

• Cars: The

smoke of the cars and the smoke of the factories rise into the atmosphere and mix with water vapor. When it rains, the rain is acid.

• Oil: They get

into the water and kill plants and wildlife in large numbers.

Wetlands

• Wetlands are very important because they

help to clean lakes and rivers. And they are in danger because people polluted it. They act like big sponges that absorb water and clean it.

Consequences of waste in water • Human and

animal waste in water produce bacteria and viruses that can make living things die.

How can we stop polluting the water?

1.Use safer stuff 2. Use natural cleansers in your home 3. Avoid using pesticides.

Don't dump it.

1. Waste not (put water in the refrigerator to keep it cold) 2. Repair leaky toilets right away.

3.Only water the yard when it really needs it.

4.Sweep off walks, don't hose them.

Conclutions • We have to stop polluting water.

• If we pollute water, we can die.

• we have to clean the rivers, ocean, etc.

• If we don’t clean water, we can kill living

things.

• We have to stop throwing petrol or oil to the water.
