What is the difference ground water and surface water?

Surface water consists of all water that is naturally exposed to the atmosphere including creeks, ponds, rivers, lakes, reservoirs, seas and oceans. Also in this category are springs and wells that are directly influenced by surface water sources.

Groundwater is water found beneath the Earth's surface that gradually seeped down by saturating soil or rock. This water is stored in underground crevices and in the pores of rocks and other materials beneath the surface.
