Landforms are natural features on Earth’s surface created by geological forces over long periods of time. A mountain is a landform because it is a raised piece of the landscape formed mainly by the movement of tectonic plates and sculpted by erosion. The other terms describe processes that change landforms: weathering breaks rocks apart, erosion carries those pieces away, and deposition settles sediments in new places. These processes shape landforms, but they aren’t landforms themselves.
