describe each layer of the atmosphere, what occurs in it, and why it is useful to the earth.
Troposphere: This layer of the atmosphere is closest to the Earth. Weather occurs here. It's useful to the Earth because this is where weather occurs...? It's also where humans live. Stratosphere: This is the second layer of the atmosphere from the Earth. A temperature inversion occurs here, and it is useful to the Earth because it contains the ozone layer, which absorbs UVC radiation. Mesosphere: This is the third layer of the atmosphere. Asteroids burn up in this layer, and noctilucent clouds form in this layer. Thermosphere: Next layer of the atmosphere.. I don't have my cheat sheet with me but if I recall correctly, there are satellites in this layer which allow for communication. Also, molecules are so far apart that they don't really act like gases anymore ¯\_(ツ)_/¯
