Explain the Greenhouse effect
Certain gases in the Earth’s atmosphere, like carbon dioxide, trap heat form the sun, warming the planet’s surface by preventing the heat from escaping back into space

What is asthma
You can turn this off when you're not using it. You can save lot's of energy.
light bulb
This energy source became even more controversial after the 2011 Fukushima disaster in Japan. Power is produced by splitting uranium atoms through a process called fission that produces heat which creates steam used to power a turbine.
nuclear power
The continuous circulation of water as it evaporates from the land and sea, enters the atmosphere, condenses and precipitates to the earth's surface, then moves underground by infiltration.
water cycle
The atmospheric layer where UV radiation from the sun is absorbed.
ozone layer (located in the Stratosphere).
Name a way you can prevent pollution
reduce, reuse, recycle, plant a tree...
Although these chemicals promote plant growth on farms, gardens, and golf courses they become extremely harmful when they enter the atmosphere and waterways.
fertilizers or pesticides
The 4th largest country in the world that consumes the most energy per capita.
China

3%
Name two natural processes that emit pollution into the air.
volcanoes and forest fires
This is one of the main reasons of water pollution. It gets on the animals skin and is hard to get it off.
oil spill
What do you call it when you take old food and worms and use them to make food for plants and trees?
