Constructive and Deconstructive Processes that shape the Earth Constructive process • A constructive process is something that adds something to the earth like a volcano that erupted and added on to an island. Deconstructive Process • A deconstructive process is a process that breaks down the earth like rain when it hits the earth for extended periods of time it breaks apart the earth. Erosion • The destructive process in which water or wind loosens and carries away fragments of rocks and or soil. Weathering • Weathering is the natural decaying or wasting of rocks, soils and their minerals at or near the surface of the earth. Landforms formed by erosion • The Grand Canyon is a landform that was formed by a river chipping a way at the earth to create a large gorge that is now the Grand Canyon.
