Question

what happens to the water pressure when water moves on a downward slope through layers of rock and soil? the water pressure decreases then increases the water pressure increases the water pressure decreases the water pressure is unchanged

Explanation:

When water moves downward through rock and soil layers, it is subject to the weight of the overlying materials. As it goes deeper (down the slope), the thickness of the overlying rock and soil increases. According to the formula for fluid pressure \(P =
ho gh\) (where \(
ho\) is the density of water, \(g\) is the acceleration due to gravity, and \(h\) is the depth of water below the surface), as \(h\) (the depth, which in this case can be related to the cumulative thickness of layers as water moves down - slope) increases, the pressure \(P\) increases.

Answer:

the water pressure increases
