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:
“... my mother ... piled up her hair and went out to teach in a one-room school, mountain children little and big alike. The first day, some fathers came along to see if she could whip their children, some who were older than she. She told the children that she did intend to whip them if they became unruly and refused to learn, and invited the fathers to stay if they liked and shed be able to whip them too. Having been thus tried out, she was a great success with them after that.”
—Eudora Welty (b. 1909)
“He was a foola brilliant man and I loved his beard, and there was the mountain ax in his brain, and all the blood poured out, and he could not see the Mexican sun. Your people raised the ax, and the last blood of revolutionary mankind, his poor blood, ran into the carpet.”
—Norman Mailer (b. 1923)
“And no one knows whats yet to come.
For Patrick Pearse had said
That in every generation
Must Irelands blood be shed.
From mountain to mountain ride the fierce horsemen.”
—William Butler Yeats (18651939)
