Destructive processes are when things happen to the earth that destroy or break down part of it. One example of a destructive process is when wind erodes or takes away some of the sand on a sand dune or beach. Erosion means that something is worn down over time. Have you ever seen a canyon? At one time, a river ran through an area. Over time, that river wore a path in the rocks. When the river dried up, the canyon was left. Sometimes humans cause parts of the earth to erode or be destroyed more quickly. Farming is a destructive process, because the soil has to be dug up and moved around in order to grow plants. Mining is another destructive process, because we dig holes into the earth or blow up parts of the earth and/or caves in order to get what we want. There are special laws in place for human actions to help protect the earth. We can still do the things we need to do, but we have to take care of the earth, too. Some destructive processes are caused by weather. Rain and wind can erode the earth, making new paths along the earth's surface.
