15 Sep 2010 But new research suggests that under the right conditions, long-lived mountain glaciers and ice caps also can facilitate the growth of mountains –
The landscape has been shaped by the river which has eroded 40 meter deep bedrock of glacial delta sediments. The vegetation includes
Mountains erode continuously. Erosion may be by water (rain or rivers), ice (glaciers) or wind. A crevasse into which rock debris is falling from the glacier's surface. With it's load of abrasive rock fragments, the base of the glacier acts like a belt sander, scraping across the rock, eroding it, producing characteristic erosional features, and creating a supply of material that leads eventually to the formation of depositional features as well. Glaciers erode terrain through two principal processes: abrasion and plucking. As glaciers flow over bedrock, they soften and lift blocks of rock into the ice. This process, called plucking, is caused by subglacial water that penetrates fractures in the bedrock and subsequently freezes and expands.
The ice and rock debris accumulates in the valleys and flows downwards as slow moving glaciers. When these melt, piles of rock debris called moraines are left behind. 2008-06-06 A valley glacier is a long, narrow glacier that forms when snow and ice build up in a mountain valley. The sides of mountains keep these glaciers from spreading out in all directions. Instead, they usually move down valleys that have already been cut by rivers.
Mountain glacier landsystem – 4 – •Mountain ice field landsystem • Cover large areas of diverse topography and can develop in a range of climatic settings • Margins carry large amounts of glaciagenic material • Ice-dammed lakes (Reference : Benn and Evans, 2010)

Why are world's highest mountains at the equator? Landforms and Cycle of Erosion.
Masses of moving ice can be two types: Moving as sheet called continental or piedmont of the glacier. Mountains erode continuously. Erosion may be by water (rain or rivers), ice (glaciers) or wind. Alpine glaciers form on mountainsides and move downward through valleys. Sometimes, alpine glaciers create or deepen valleys by pushing dirt, soil, and other materials out of their way.

26 Feb 2018 Glaciers create some of Earth's steepest topography; yet, many areas that were repeatedly overridden by ice sheets in the last few million years
About 90% of the glaciers are of the mountain type and 10% are valley trough type (Table 5.6).But the area covered by the mountain type is about 40%, while the valley type covers an area of > 60%.Similarly, the ice reserves contribution is around 84%. Glaciers cover about 10% of the surface of the Earth, and are powerful erosional agents that sculpt the planet’s surface.
