Introduction

A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (980 ft) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges.
Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers.
High elevations on mountains produce colder climates than at sea level at similar latitude. 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, such as mining and logging, along with 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). The tallest mountain including submarine terrain is Mauna Kea in Hawaii from its underwater base at 9,330 m (30,610 ft); some scientists consider it to be the tallest on earth. (Full article...)

A glacier (US: /ˈɡleɪʃər/; UK: /ˈɡlæsiə/ or /ˈɡleɪsiə/) is a persistent body of dense ice, a form of rock, that is constantly moving downhill under its own weight. A glacier forms where the accumulation of snow exceeds its ablation over many years, often centuries. It acquires distinguishing features, such as crevasses and seracs, as it slowly flows and deforms under stresses induced by its weight. As it moves, it abrades rock and debris from its substrate to create landforms such as cirques, moraines, or fjords. Although a glacier may flow into a body of water, it forms only on land and is distinct from the much thinner sea ice and lake ice that form on the surface of bodies of water.
On Earth, 99% of glacial ice is contained within vast ice sheets (also known as "continental glaciers") in the polar regions, but glaciers may be found in mountain ranges on every continent other than the Australian mainland, including Oceania's high-latitude oceanic island countries such as New Zealand. Between latitudes 35°N and 35°S, glaciers occur only in the Himalayas, Andes, and a few high mountains in East Africa, Mexico, New Guinea and on Zard-Kuh in Iran. With more than 7,000 known glaciers, Pakistan has more glacial ice than any other country outside the polar regions. Glaciers cover about 10% of Earth's land surface. Continental glaciers cover nearly 13 million km2 (5 million sq mi) or about 98% of Antarctica's 13.2 million km2 (5.1 million sq mi), with an average thickness of ice 2,100 m (7,000 ft). Greenland and Patagonia also have huge expanses of continental glaciers. The volume of glaciers, not including the ice sheets of Antarctica and Greenland, has been estimated at 170,000 km3.

Selected mountain range
The Ślęża (Polish: [ˈɕlɛ̃ʐa]; German: Zobten or Zobtenberg, later also Siling) is a 718 m (2,356 ft) high mountain in the Sudeten Foreland in Poland. The mountain is built mostly of granite and is covered with forests.
The top of the mountain has a PTTK tourist mountain hut, a television and radio mast, the Church of the Visitation of the Blessed Virgin Mary, some poorly-visible ruins of the castle and an observation tower. The area of the peak is protected as the Góra Ślęża nature reserve. The wide area around the mountain forms the Ślęża Landscape Park protected area. (Full article...)

Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth. Although most submarine volcanoes are located in the depths of seas and oceans, some also exist in shallow water, and these can discharge material into the atmosphere during an eruption. The total number of submarine volcanoes is estimated to be over one million (most are now extinct) of which some 75,000 rise more than 1 kilometre (0.62 miles) above the seabed. Only 119 submarine volcanoes in Earth's oceans and seas are known to have erupted during the last 11,700 years.
Hydrothermal vents, sites of abundant biological activity, are commonly found near submarine volcanoes. (Full article...)
Selected climbing article
The development of rock-climbing techniques was as important as the development of rock-climbing equipment in increasing standards and reaching new grade milestones. Several techniques were particularly notable for their impact on the sport — and on particular types of climbing routes — and are key for any aspiring rock climber to master. The development of route setters in competition climbing, who can artificially fine-tune a route to require the accurate use of specific techniques, has further increased the range of techniques that contemporary rock climbers need to master.

Ski and Snowboarding Foundation Nepal is non profit and non governmental organisation established in 2016 with the aim of developing skiing and snowboarding culture in Nepal. Since its establishment, the foundation has organized events, training, research and camps in different places of Nepal. Ski and Snowboarding Foundation Nepal installed the first ski lift in Nepal in Kalinchowk. Ski and Snowboarding Foundation Nepal was founded by Utsav Pathak and Julious Seidenador in 2016. Ski and Snowboarding Foundation Nepal has been working from Humla to Solukhumbu. They have also been featured in many international magazines and have been nominated for UIAA 2022 Mountain Protection Award.
Ski and Snowboarding Foundation is also known as NFSS among ski and snowboarding community in Nepal (Full article...)
