Glaciology is an interdisciplinary Earth science that integrates geophysics, geology, physical geography, geomorphology, climatology, meteorology, hydrology, biology, and ecology. The impact of glaciers on people includes the fields of human geography and anthropology .
Alpine glaciers form on the crests and slopes of mountains. A glacier that fills a valley is called a valley glacier, or alternatively, an alpine glacier or mountain glacier. [9] A large body of glacial ice astride a mountain, mountain range, or volcano is termed an ice cap or ice field. [10]
There are eighteen small glaciers in the North Island on Mount Ruapehu. [13] An inventory of South Island glaciers compiled in the 1980s indicated there were about 3,155 glaciers with an area of at least one hectare (2.5 acres). [14] Approximately one sixth of these glaciers covered more than 10 hectares. These include: Fox Glacier; Franz Josef ...
A NASA study revealed a glacier that was one of the fastest-shrinking ice and snow masses on Earth is making an unexpected comeback. A NASA study revealed a glacier that was one of the fastest ...
Apart from the landforms left behind by glaciers, glaciers themselves are striking features of the terrain, particularly in the polar regions of Earth. Notable examples include valley glaciers where glacial flow is restricted by the valley walls, crevasses in the upper section of glacial ice, and icefalls—the ice equivalent of waterfalls.
Plucking is increased where there are preexisting fractures in a rock bed. As the glacier slides down a mountain, energy from friction, pressure or geothermal heat causes glacial meltwater to infiltrate the spaces between rocks. [4] This process, known as frost wedging, puts stress on the rock structure as water expands when it freezes.
Glacier tourism has boomed in recent years. The ice attracts people for many reasons: to fulfill a bucket list dream, get up close to a natural phenomenon, or simply for adventure.
All articles about glaciers, glaciology, geologic and geographical impacts from glaciers, as well as climatological articles directly related to glaciers. The Malaspina Glacier is so large that it can only seen in its entirety from space; this 1994 photo from STS-66, on a rare clear day, is of an area about 100 km (60 mi) across.
