what is infiltration
Answers
Answer: Infiltration is the process by which precipitation or water soaks into subsurface soils and moves into rocks through cracks and pore spaces. As we mentioned before, the bulk of rainwater and melted snow end up infiltrated. As we mentioned before, the bulk of rainwater and melted snow end up infiltrated.
Explanation: Water can be absorbed by the soil and may stay in the soil for a long time until it gradually gets evaporated. If there is a lot of vegetative cover (green plants) the infiltrated water can also be absorbed by plant roots and later transpired. Infiltration occurs in the upper layers of the ground but may also continue further downwards into the water table.

Answer:
Infiltration is the process by which water on the ground surface enters the soil.
Infiltration is governed by two forces, gravity, and capillary action.
While smaller pores offer greater resistance to gravity, very small pores pull water through capillary action in addition to and even against the force of gravity.
Infiltration rate in soil science is a measure of the rate at which a particular soil is able to absorb rainfall or irrigation.
It is measured in inches per hour or millimeters per hour.
The rate decreases as the soil becomes saturated.
If the precipitation rate exceeds the infiltration rate, runoff will usually occur unless there is some physical barrier.
It is related to the saturated hydraulic conductivity of the near-surface soil.
