INDIAN GEOGRAPHY

Detailed explanation-1: -The Correct answer is Infiltration. Important Points. Soil infiltration refers to the soil’s ability to allow water movement into and through the soil profile.

Detailed explanation-2: -Infiltration is the process of water entry into the soil through the earth’s surface. The water at the soil surface can originate from rain, snowmelt or anthropogenic activities (e.g. to regulate groundwater formation by artificial infiltration).

Detailed explanation-3: -Infiltration is the downward entry of water into the soil. Infiltration rate is expressed in inches per hour. Rainwater must first enter the soil for it to be of value. Water moves more quickly through the large pores of a sandy soil compared to slower movement through a clay soil with small pores.

Detailed explanation-4: -Infiltration is the physical process involving movement of water through the boundary area where the atmosphere interfaces with the soil. The surface phenomenon is governed by soil surface conditions. Water transfer is related to the porosity of the soil and the permeability of the soil profile.

Detailed explanation-5: -Subsidence is a general term for downward vertical movement of the Earth’s surface, which can be caused by both natural processes and human activities. Subsidence involves little or no horizontal movement, which distinguishes it from slope movement.
