Final answer:
The amount of moisture mainly supplied by evaporation from oceans and other bodies of water is water vapor.
Step-by-step explanation:
The amount of moisture mainly supplied by evaporation from oceans and other bodies of water is water vapor. When water evaporates, it changes from a liquid to a gas and becomes water vapor.
This water vapor remains in the atmosphere until it undergoes condensation and then precipitation, which can be rain, sleet, hail, or snow.
