Mountain

A mountain is a landform that extends above the surrounding terrain in a limited area. A mountain is generally higher and steeper than a hill, but there is considerable overlap, and usage often depends on local custom.
Mountains cover 52% of Asia, 36% of North America, 25% of Europe, 22% of South America, 17% of Australia, and 3% of Africa. As a whole, 24% of the Earth's land mass is mountainous. Also, 1 in 10 people live in mountainous regions. All the world's major rivers are fed from mountain sources, and more than half of humanity depends on mountains for water.
The adjective montane is used to describe mountainous areas and the things associated with them.
