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:
“Again, he felt a crude ecstasy. He could not have given the reason, but the mountain tormented him, beckoned him, held an answer to something he wanted. It was so pure, so austere.”
—Norman Mailer (b. 1923)
“The mountain sheep are sweeter,
But the valley sheep are fatter;
We therefore deemed it meeter
To carry off the latter.”
—Thomas Love Peacock (17851866)
“The moon was waiting for her chill effect.
I looked at nine: the swarm was turned to rock
In every lifelike posture of the swarm,
Transfixed on mountain slopes almost erect.”
—Robert Frost (18741963)
