Question

The Grand Canyon is one of Arizona’s most popular tourist attractions. This massive canyon was formed over 6 million years ago. In three short sentences, explain how valleys and mountain ranges are formed.

Answer 1

Valleys and mountain ranges are formed through geological processes such as tectonic plate movements, erosion, and sediment deposition. When tectonic plates collide, they can push the Earth's crust upward to create mountains, while areas of lower elevation can develop into valleys due to erosion or subsidence. Over time, the forces of wind and water further shape these landscapes, carving out valleys and sculpting mountain features.
