Hard to reach pothole arches are formed when a small pit on top of rock meets in the middle with an opening on the side of a rock wall. While the rainfall average is very low, the rains that do come to the park tend to arrive as rainstorms that often cause flash flooding. Ocean trenches are a result of tectonic activity, which describes the movement of the Earths lithosphere. They do this by releasing sperm and eggs (calledgametes) into the water.
