When precipitation falls on land surfaces, it begins to flow toward sea level. the water is more likely to flow toward sea level as groundwater if a. the surface is not porous and there are few interconnected spaces underground. b. the surface is porous and there are few interconnected spaces underground. c. the surface is not porous and there are lots of interconnected spaces underground. d. the surface is porous and there are lots of interconnected spaces underground.

The answer is; D

If the ground is porous, the water from precipitation is able to permeate into the ground to the water table. If there are interconnected spaces in the underground, the underground water is able to flow slowly and steadily beneath the ground until it gets to sea level.
