Geography

Plate Tectonics and Mountain Formation

Mountains form when tectonic plates collide. The Himalayas are still growing as India pushes into Asia. The Appalachians were once Himalaya-height but have eroded over 300 million years. Fold mountains, volcanic mountains, and fault-block mountains form differently.

Mount Everest grows about 4 millimeters every year as India continues pushing north!
