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.

Events such as landslides, volcanoes, tsunamis and earthquakes can change a landscape in the blink of an eye.hile these slope failures can happen due to natural causes such as torrential rain or earthquakes, they can also be caused by human activity such as machinery blasting that weakens the ground. 1  In the right-center of the picture to the left we see an example of slope failure leading to a landslide in India.
