Seventy-five percent of the crust of the Earth is covered with water, so there must be some nearby.
Water can be tremendously forceful.
Water in motion can cause great changes in the appearance of the crustal plates. Over millions of years, the forceful rush of water can cut deep canyons into dry desert rock. The Grand Canyon, in Arizona, for example, was carved by water. Falling water, also, can shape the landscape. The pounding force of a waterfall erodes, or wears down, the rock beneath the water.
