A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 meters (980 feet) above the surrounding land. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Here are some fun online games tagged with the keyword mountain.
