1. Climate Change

2. Water

3. How Old Is Water? Water has been around for millions of years and is almost as old as the Earth. When you look at your glass of water, the water may have only rained from a cloud last week it is still older than you think.

4. How Did Rain Get To Earth? Millions of years ago lots of comets hit Earth. Comets are made up of water, so with Just the right amount of comets it can form our oceans today.

5. How Do Clouds Turn Into Rain? This is known as the water cycle, the hydrologic cycle or the H2O cycle. When it rains it means one of the clouds has condensed into water. First water will start in a pond, lake, river or ocean then when it is warm it will evaporate into steam. The steam will float into the air and form clouds. This is called evaporation. Next the cloud will find a cold wind and slowly condense into a liquid. This is called condensation. This is known as the water cycle, the hydrologic cycle or the H2O cycle.

6. The Ozone Layer

7. How Does The Ozone Layer Protect Us The Ozone Layer is a thick layer of gas surrounding the Earth. It helps protect us from harmful sunrays that can burn skin and cause skin cancer. Currently there is a hole in the Ozone layer in Antarctica. The bigger the hole the more the heat will rise. The Ozone Layer is a thick layer of gas surrounding the Earth.

8. How Can We fix The Hole In The Ozone layer The hole is caused by greenhouse gasses and CO2. The only way to stop this is by using less harmful gasses. To help we can try to reduce the amount of time we spend in a car. The hole is caused by greenhouse gasses and CO2. The only way to stop this is by using less harmful gasses.

9. Why Is The Hole Getting Bigger? The hole in the ozone layer is getting larger because we are using more and more harmful gasses everyday and that will effect the hole. This hole is also causing Antarctica and the North pole to slowly melt away. This will make the penguins, polar bears and other animals that live there to lose their habitats.

10. Droughts

11. What Causes A Drought? A drought can be caused by less rainfall. All the crops and wheat will die. A drought will usually happen in drier countries. Droughts can cause starvation and can kill a hole crop of wheat. A drought can be caused by less rainfall. All the crops and wheat will die. A drought will usually happen in drier countries. Droughts can cause starvation and can kill a hole crop of wheat.

12. Why Does A Drought Kill Crops? The heat in a drought is to much for a plant, causing it to wither. When crops die there can be a lot of problems for food supply. This does not only affect the food supply, it also affects the countries trade. For instance if England wanted to sell a ton of wheat to New Zealand but they had a drought, they couldn’t grow the wheat. The heat in a drought is to much for a plant, causing it to wither.

13. What Part Of The Year Would There Be A Drought? Droughts would usually happen in the summer but can also be in another season too. Droughts cause the climate to rise which means they are more common in summer. Recently there was a drought in North America. The drought started in spring 2012.
