The geological layer that consists of underground caverns and porous layers of sand, gravel or bedrock where groundwater flows is called an aquifer. The zone of saturation is the area below the water table where all the pores and spaces in the soil and rock are completely filled with water. The water table is the boundary between the unsaturated and saturated zones, and surface water refers to streams, rivers, lakes, and other sources of water that are on the surface of the Earth. Bedrock is the solid rock layer that underlies the soil and other loose material on the surface.
