A landform is any natural formation of rock and dirt, found on Earth. A landform can be as large as a mountain range, or as small as a hill. It can be as large as a continent, or as small as a pond.
Landforms are defined as the natural physical features found on the surface of the earth. Landforms are created as a result of the various forces of nature such as wind, water and ice and also by the movement of the earthâs tectonic plates. For example, due to these actions, the soil gets eroded and deposited somewhere far from the site of erosion, thus leads to the formation of different landforms.
