Plants contribute to the water cycle through this process.
transpiration
the gas form of water
Water Vapor
Where does most of the earths evaporation come from
oceans
What force pulls water from clouds down to earth in the form of precipitation?
Gravity
What causes clouds to form?
Water vapor rising into the air and cooling back into liquid water drops.

precipitation
Explain why sweating cools you off
Evaporation takes energy (heat) away with the water vapor

What are two elements that make up water, and how many atoms of each are required?
2 hydrogen & 1 oxygen atoms
Name 2 processes that absorb energy in order to happen
What are evaporation and transpiration
What is the equation for relative humidity?
Amount of water in the air / Total water vapor that the air can hold
