The change from a gas to a liquid is called this
What is Condensation
100
The sun does this to the earth.

The change from a liquid to a gas is called this.
What is Evaporation
200
Most people find that a humidity reading of this percent to be most comfortable.
What is 50-60%
200
Cool air does this
What is Sinks
200
Condensation can happen when this happens to warm moist air.
What is when it cools
200
When the water on the earth heats up is causes it to
What is Evaporate
300
Evaporation can be affected by three things: wind, the amount of liquid water, and this.
What is Heat

The temperature at which water vapour in the air starts to condense is called this.
What is Dew Point
400
Name three forms of precipitation
What is Snow, Rain, Sleet, Hail, Freezing Rain
500
If the humidity reading is 30%, it means this percent of the air is not holding moisture.
