2. Atmospheric Moisture Exists in Three States Solid: Ice Crystals
Liquid: Water droplets
Gas: Water Vapor

3. How does water enter the Atmosphere?
***Evaporation***
Sublimation
Transpiration: product of photosynthesis; plants release water into the air

5. Factors Affecting the Rate of Evaporation
1. Amount of Energy Available
2. Surface Area of Water
3. Degree of Saturation
4. Wind Speed

6. 1. Amount of Energy Available
