    Deposition is the geological process in which sediments, soil and rocks are added to a landform or landmass. Wind, ice, water, and gravity transport previously weathered surface material, which, at the loss of enough kinetic energy in the fluid, is deposited, building up layers of sediment.

  9. Subsurface flow - Wikipedia

    en.wikipedia.org/wiki/Subsurface_flow

    In the water cycle, when precipitation falls on the Earth's land, some of the water flows on the surface forming streams and rivers. The remaining water, through infiltration , penetrates the soil traveling underground, hydrating the vadose zone soil, recharging aquifers , with the excess flowing in subsurface runoff.
