Question

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

Explanation:

Water pressure depends on depth ($P =
ho gh$, where $
ho$ is density, $g$ is gravity, $h$ is depth). When water moves downward, depth increases, so pressure increases.

Answer:

the water pressure increases
