Detailed explanation-1: -Most of it (80 percent) evaporates or transpires. The rest runs into streams, rivers and dams (surface water) or soaks into the ground (groundwater). Infiltration. Infiltration happens when water soaks into the soil from the ground level.

Detailed explanation-2: -Movement of water into soil is called infiltration, and the downward movement of water within the soil is called percolation, permeability or hydraulic conductivity. Spaces in soil, between the mineral and organic matter, that are filled with water or air.

Detailed explanation-3: -Runoff is precipitation that does not soak into the soil but instead moves on the Earth’s surface toward streams. Streamflow is water moving across the Earth’s surface in streams. Evaporation refers to water that changes from a liquid to a gas and moves from the Earth’s surface back into the atmosphere.

Detailed explanation-4: -Recharge. The rest of it soaks or percolates into the soil, called recharge. The water then moves down through the soil as groundwater and is stored in the aquifer below.
