A mountain is considered to be a large land form that extends above the surrounding land in a limited area, usually ending in the form of a peak. Mountains are generally steeper than hills. Mountains are formed through tectonic forces or volcanism. These forces can raise the surface of the earth locally. 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.
High elevations on mountains produce colder climates than at sea level. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and climate, mountains tend to be used less for agriculture and more for resource extraction and recreation, such as mountain climbing.
The highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m/29,035 ft above sea level.
“I wonder if the snow loves the trees and fields, that it kisses them so gently? And then it covers them up snug, you know, with a white quilt; and perhaps it says, “Go to sleep, darlings, till the summer comes again.”
― Lewis Carroll,
“And finally Winter, with its bitin’, whinin’ wind, and all the land will be mantled with snow.”
