Glaciers | PPT - SlideShare
2017年5月7日 · Glaciers are large, thick masses of ice formed from compacted snow that accumulates over many years. Glaciers form in areas where snow accumulation exceeds melting. Due to their great mass, glaciers slowly flow downhill like rivers. Glaciers erode the underlying landscape and form characteristic landforms as they advance and retreat.

Glacial landforms (geomorphology) | PPT - SlideShare
2018年12月9日 · Glaciers powerfully erode, transport, and deposit sediment. They carve U-shaped valleys and leave behind landforms like moraines, drumlins, eskers and kettle lakes. Glaciers shape mountain and coastal landscapes through erosion and deposition.

Glacier Slide - Earth Science Week
Glacier Slide. Activity Source: National Park Service. Objective. You will be able to describe how a glacier carves an area and label the characteristics formed by the glacier’s movement. Background. There are many glaciers all over Alaska. Flying into Lake Clark National Park and Preserve through Lake Clark Pass, you will see many glaciers.

Deformation and sliding - AntarcticGlaciers.org
2020年6月22日 · Glaciers can slide because ice melts under pressure, resulting in a film of water at the ice-bed interface. This can facilitate decoupling and enhance fast ice flow.
Glacial motion - Wikipedia
Glacier motion occurs from four processes, all driven by gravity: basal sliding, glacial quakes generating fractional movements of large sections of ice, bed deformation, and internal deformation. In the case of basal sliding, the entire glacier slides over its bed.
