• Situated at the top of the ionosphere

• Cooler than the layers surrounding it

• More than 100 km in thickness

The atmosphere is...

• The layer in which weather occurs

• The layer that contains the ozone layer

• The layer of water in the oceans

• The layer of gases that surrounds Earth

Earth’s atmosphere is important to living things because it…
