Answer:
Well there are many different kinds of landforms found in North America.
Landforms may be classified as depositional or erosional. Depositional landforms have the character and shape of the deposits of which they are made. They include beaches, stream terraces, and alluvial fans at the foot of mountains. Erosional landforms are ones that have been created by agents of erosion such as streams, rain, and ice. The most widespread erosional landforms are those made by running water acting over very long periods of time.
