Answer 1

Evaporation:- it is a process of vaporization which occurs on the water surface and changes into gas. In this process the surrounding gases must not be saturated with evaporating substance. It is a cooling process.

Evapotranspiration:- it the process of transfer of water from the land to atmosphere by evaporation and transformation of water from plant to atmosphere by transportation.

Potential evaporation:-also known as potential evapotranspiration (PET) is the amount of evaporation takes place when sufficient water source is available. It is the total results by atmospheric demand for moisture from surface and ability of surface to supply moisture content.

Evaporation of an any body(except water) that contains water is greatly controlled by porosity, permeability. In water bodies the factors are temperature, humidity , availability of surrounding pressure , amount of water available. All these factors which are controlled the evaporation characteristics on a water bodies.
