cold dense air sinks towards surface of Earth, warming the air, making it able to hold more water vapor. therefore, little precipitation |
|
|
How Greenhouse effect works |
-sun emits ultraviolet and visible electromagnetic radiation energy -short radiation waves pass through earths gas molecules -UV and visible electromagnetic energy absorbed by earth, warming surface -warm earth emits infrared EM radiation -these longer waves are absorbed by gases in atmosphere |
