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 and the squirrel
Had a quarrel,
And the former called the latter “Little Prig”;”
—Ralph Waldo Emerson (1803–1882)
“There is a mountain in the distant West
That, sun-defying, in its deep ravines
Displays a cross of snow upon its side.
Such is the cross I wear upon my breast
These eighteen years, through all the changing scenes
And seasons, changeless since the day she died.”
—Henry Wadsworth Longfellow (1809–1882)
“Fogs and clouds which conceal the overshadowing mountains lend the breadth of the plains to mountain vales. Even the small-featured country acquires some grandeur in stormy weather when clouds are seen drifting between the beholder and the neighboring hills.”
—Henry David Thoreau (1817–1862)
