Tear it down Build it up. Destructive Processes are when things happen to the earth that destroy or break down part of it. One example of a destructive process is a river wearing away the rocks and dirt to form a canyon. In the story, an example of a destructive process was the erosion that carried the dirt and the minerals from rocks down into the cave. Weathering is the process that breaks rocks down into pieces called sediment.
However, certain subtle processes like weathering change the earth's surface slowly. âº Destructive forces mainly lead to erosion and weathering of rocks. âº In erosion, soil particles are stripped away by water, wind, ice, and gravity over time. Erosion implies movement of sediment from one place to another. The boring, scraping, burrowing, and grinding of organisms results in the erosion of hard ocean as well as terrestrial substrates.
