Introduction

Appalachian Mountains
Mount Ararat, as seen from Armenia

A mountain is a large landform that rises above the surrounding land in a limited area, usually in the form of a peak. A mountain is generally considered to be steeper than a hill. Mountains are formed through tectonic forces or volcanism. These forces can locally raise the surface of the earth. 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 and skiing.

The highest mountain on Earth is Mount Everest in the Himalayas of Asia, whose summit is 8,850 m (29,035 ft) above mean sea level. The highest known mountain on any planet in the Solar System is Olympus Mons on Mars at 21,171 m (69,459 ft).

Skeiðarársandur in Iceland, viewed from its eastern margin at the terminus of Svínafellsjökull glacier

An outwash plain, also called a sandur (plural: sandurs), sandr or sandar, is a plain formed of glacial sediments deposited by meltwater outwash at the terminus of a glacier. As it flows, the glacier grinds the underlying rock surface and carries the debris along. The meltwater at the snout of the glacier deposits its load of sediment over the outwash plain, with larger boulders being deposited near the terminal moraine, and smaller particles travelling further before being deposited. Sandurs are common in Iceland where geothermal activity accelerates the melting of ice flows and the deposition of sediment by meltwater. Read more...

Selected mountain range

Pine Mountain Ridge (or simply Pine Mountain) is a massif of the Transverse Ranges located in northern Ventura County, and entirely within the Los Padres National Forest. The ridge is a large block of Matilija Sandstone, and reaches some of the highest elevations in the southern Transverse Ranges. The north slope of the ridge is part of the Sespe Wilderness.

Major peaks on the ridge include, from west to east, Reyes Peak, Haddock Peak, and Thorn Point. Read more...

Fjäll landscape in Padjelanta, Swedish Lapland

Man climbs a tree

Tree climbing is a recreational or functional activity consisting of ascending and moving around in the crown of trees.

A rope, helmet, and harness can be used to ensure the safety of the climber. Other equipment can also be used depending on the experience and skill of the tree climber. Some tree climbers take special hammocks called "Treeboats" and Portaledges with them into the tree canopies where they can enjoy a picnic or nap, or spend the night. Read more...
