Answer:
B. Underground water close to the surface of the land
Explanation:
The water table is the underground dividing line between the unsaturated zone in the upper layer and the saturated zone in the lower layer. The unsaturated zone is the soil surface and zone of aeration where oxygen and water permeate through the soil. The saturated zone is composed of hard rock. When water precipitates from the soil, the result is the groundwater found below the water table.
Groundwater overflows as springs into water bodies at the point where the land surface converges with the water table. Therefore, regions with high table water will have their underground water close to the land surface.
