Mountains

Most geologists classify a mountain as a landform that rises at least 1,000 feet (300 meters) or more above its surrounding area.  A mountain range is a series or chain of mountains that are close together.

The tallest mountains are formed when pieces of Earth’s crust–called plates–smash against each other (a head-on car collision) and cause the land to buckle upward. 

The Himalaya Mountains, for example, formed because of the subduction of the Indian tectonic plate with the Eurasian plate (subduction is when one plate slides under another, forcing the land upward).
