Moisture transfer from plants to the atmosphere is called (a)   .

Evaporation and transpiration are collectively known as

(a)  

There are two conditions required for evaporation to occur:

• availability of energy and water

• the air above the water bodies is not saturated

• the air above the water bodies is saturated

• availability of oxygen and carbon dioxide in the air

___________________ is the amount of water vapour held in the atmosphere. It can be expressed in grams of water vapour per cubic metre of air.

• Relative humidity

• humidity

• humid

Relative humidity is the ratio of the actual amount of water vapor in the air in relation to the maximum water-holding capacity of the air at a certain air temperature. It is expressed as ______________.
