Ch. 4: Global Climates and Biomes
The Unequal Heating of Earth
Atmospheric Layers & Properties
3rd Layer: Mesosphere
atmospheric pressure and density is less than that of the stratosphere
4th Layer: Thermosphere
atmospheric pressure and density is less than that of the mesosphere
blocks harmful X-ray and UV radiation
contains charged molecules that produce light when solar energy hits them
most noticeable in North and South Pole
(North Pole - aurora borealis; South Pole - aurora australis)
2nd Layer: Stratosphere
10-31 miles above earth
less dense than troposphere
Ozone (O3) Layer (a sky-blue gas) forms a layer here and converts UV radiation (most of UV-B and all of UV-C) into infrared radiation
warmer in upper stratosphere than lower stratosphere
5th Layer: Exosphere
atmospheric pressure and density is less than that of the thermosphere
1st Layer: Troposphere
extends 10 miles above earth
densest layer of the atmosphere b/c lots of liquids and gases circulate here
most of the nitrogen, oxygen and water vapor exists here
