What are three different types of landforms?
Landforms are dominant geographical features that tend to define a particular region. Landforms are caused by geological and climate forces over the period of millions of years. Some common landforms are mountains, canyons, mesas, and caves. Mountains are formed when tectonic plates collide and thrust the earth's crust upward. Canyons are formed by the erosion of constantly flowing water over the same rocks and soil over a long periond of time. Mesas are elevated pieces of land that have flat tops and steep sides. They are formed by water erosion of uplifted rocks and are found in desert regions. Caves are formed by water seeping into the ground and dissolving minerals from the rocks, thus forming open caverns underground.
