On a beach, I saw a waterway descending from the hills to the sea. It is reminiscent of a geography lesson of a transformation of the Earth's surface, called exogenous power, a power derived from external factors such as water, wind and weather.
One kind of this exogenous power is erosion, which is a process of releasing or transferring the mass of rocks naturally from one place to another by a substance that moves on the surface of the earth. One of these substances is water, and the mechanics of erosion caused by water are exhibited in the waterway, which I saw there; it erodes, subverts, transfers, creates new formats.
