What is our climate system?
Atmosphere:
The atmosphere covers the Earth.
It is a thin layer of mixed gases which make up the air we breathe.
This thin layer also helps the Earth from becoming too hot or too cold.
Oceans:
Oceans cover about 70 percent of Earth's surface.
Their large size and thermal properties allow them to store a lot of heat.
Land:
Land covers 27 percent of Earth's surface and land topography influences weather patterns.
Ice:
Ice is the world's largest supply of freshwater.
It covers the remaining 3 percent of Earth's surface including most of Antarctica and Greenland.
Ice plays an important role in regulating climate, because it is highly reflective.
Biosphere:
The biosphere is the part of Earth's atmosphere, land, and oceans that supports any living plant, animal, or organism.
It is the place where plants and animals, including humans, live.
