A mountain is a large landform that stretches above the surrounding land in a limited area usually in the form of a peak. A mountain is generally steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth by over 10,000 feet (3,000 m). Mountains erode slowly through the action of rivers, weather conditions, and glaciers. A few mountains are isolated summits, but most occur in huge mountain ranges.
The highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,848 m (29,029 ft) above mean sea level. The highest known mountain in the Solar System is Olympus Mons on the planet Mars at 21,171 m (69,459 ft).

Famous quotes containing the word mountain:
“The mountain held the town as in a shadow.”
—Robert Frost (1874–1963)
“The most stupendous scenery ceases to be sublime when it becomes distinct, or in other words limited, and the imagination is no longer encouraged to exaggerate it. The actual height and breadth of a mountain or a waterfall are always ridiculously small; they are the imagined only that content us.”
—Henry David Thoreau (1817–1862)
“The mountain may be approached more easily and directly on horseback and on foot from the northeast side, by the Aroostook road, and the Wassataquoik River; but in that case you see much less of the wilderness, none of the glorious river and lake scenery, and have no experience of the batteau and the boatman’s life.”
—Henry David Thoreau (1817–1862)
