3
Q
Thermosphere
A
temperature increases due to absorption of high energetic solar radiation, hottest place on earth
4

temperature decreases because density decreases, leaving fewer molecules to absorb the sun, coldest place on earth
5
Q
Stratosphere
A
temperature increases because the top layer of stratosphere is warmed by UV rays
6
