Click to go to this website to learn about the three main cloud types.

#3 How do clouds form? Put these sentences in order, check yourself, and rescramble before moving on.

Sun heats the earth and water evaporates into water vapor.

The hot, moist air rises and cools.

The air cools until it is satuared (cool air can't hold as much water vapor as warm air).

Clouds form when the water vapor condenses (100% relative humidity).

If the water droplets cling together and get heavy enough, it rains!

(absorbed from the environment)

#7 Temperature of the Atmosphere

The sun heats the earth, the earth heats the air above it.

If you were lying on the ground under the cold air, you would feel higher pressure. WHY?
