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:
“Nor has science sufficient humanity, so long as the naturalist overlooks the wonderful congruity which subsists between man and the world; of which he is lord, not because he is the most subtile inhabitant, but because he is its head and heart, and finds something of himself in every great and small thing, in every mountain stratum, in every new law of color, fact of astronomy, or atmospheric influence which observation or analysis lay open.”
—Ralph Waldo Emerson (18031882)
“We are wearied of our huts
And the smoky smell of our garments.
We are sick with desire of the sun
And the grass on the mountains.”
—Unknown. The Grass on the Mountain (l. 1114)
“I thought of Chatterton, the marvellous boy,
The sleepless soul that perished in his pride;
Of him who walked in glory and in joy
Following his plough, along the mountain side:
By our own spirits are we deified:
We poets in our youth begin in gladness;
But thereof come in the end despondency and madness.”
—William Wordsworth (17701850)
