The process of conversion and transfer of moisture in the atmosphere to the land is called as
The water which is retained by plant surfaces, and which is later
evaporated away or absorbed by the plant is called as-
Interception loss
interception water
interception evaporation
The water which trickles along twigs and branches and finally down the main trunk. Name the process
Stem flow
interception evaporation

Tundra
The process by which water vapors escapes from living plants, mainly from the leaves, and enters the atmosphere is called as
The process by which water soaks into or is absorbed by the soil is called as
On bare soils where rain splash impact occurs, infiltration rates may reach 10_mm_h–1. On similar soils covered by vegetation rates will be increased or decreased
The process by which vapour passes into a liquid form and it occurs when air is cooled to its dew point or becomes saturated by evaporation into it is called as

As salinity increases, water becomes denser. As pressure increases, water becomes
Denser
Lesser Dense
Stable
No changes
