Which statement explains what happens at the water table?

A) Water rises to a place above the surface where people can collect it and use it for drinking water.

B) Materials such as clay or granite prevent water from seeping into the ground at the water table.

C) A boundary forms between an area filled with water and an area with both moisture and air.

D) Water from rivers, lakes, and streams seeps into the ground and saturates it to reach the water table.

C) A boundary forms between an area filled with water and an area with both moisture and air.

Explanation:

The water table is the boundary between the water saturated zone and unsaturated zone underground. Water table is the upper surface of the zone of saturation. In the water level zone the absolute pressure equals the atmospheric pressure and the relative pressure. The saturated zone, the fractured portion and pores of the rocks is filled with water.

The water table region demarcate the boundary where water surrounds the pores or fracture of the rock (aquifer) and the region that lacks abundant water (unsaturated). The upper area which is the unsaturated region contains both air and moisture.

the right answer is C
