Which process describes the movement of rainwater seeping through soil and into the ground?

The process that describes the movement of rainwater seeping through soil and into the ground is known as infiltration. This occurs when water from precipitation falls to the surface and begins to permeate through the soil layers, allowing it to enter the ground. Infiltration is an essential component of the hydrological cycle, as it replenishes groundwater supplies and supports ecosystems by providing moisture to plant roots.

Focusing on the context of the other processes, precipitation refers to the various forms of water, such as rain, snow, sleet, or hail, that fall from the atmosphere to the Earth's surface. Evaporation is the process by which water changes from a liquid to a gas, typically from surface water bodies into the atmosphere. Collection refers to the accumulation of water in bodies such as rivers, lakes, and oceans after it has fallen as precipitation. Infiltration is distinct from these processes as it specifically addresses how water moves into the soil, making it the most accurate answer.
