Thermosphere?

400

Earth's temperature would be very what without the atmosphere?

Low

400

The greenhouse effect

The warming of the surface and lower atmosphere of Earth that occurs when water vapor, carbon dioxide, and other gases absorb and reradiate thermal energy

500
The Ozone layer is in this layer.
What is the Stratosphere?
500

What are the 3 functions of the atmosphere?

1. Protect living things from harmful UV rays

2. Keeps earth warm enough for life to exist

3. Liquid water is present with temperature ranges

500
