What I Have Learned

I have learned that water vapor is water in the state of gas.Humidity is the amount of water in the air.Air pressure decreases as the altitude increases.
I also know how the water cycle works.Water cycle means movement of water through the hydrosphere,geosphere, and atmosphere.Condensation is when gas is changed to a liquid.Precipitation is rain,snow,sleet,or hail.A run-off is water that runs off Earth's surface,evaporation is when a liquid is changed to a gas.Groundwater is water in the ground.
I know what the three types of clouds are.A puffy,flat based cloud is a cumulus cloud.A feathery cloud is a cirrus cloud.And a blanket like cloud is a stratus cloud.
As you can see this is all of the things i have learned so far.
