WebGlaciers move because the surface of the ice is sloped. This generates a stress on the ice, which is proportional to the slope and to the depth below the surface. As shown in Figure 16.12, the stresses are quite small near … WebDec 25, 2024 · The streams may or may not be incised into valleys on the glacier surface; that depends on the relative rates of channel downmelting and interchannel ablation. Meltwater streams on glacier-ice surfaces have a strong tendency to form meanders, much like streams flowing on land. includes what

WebGlaciers move by internal deformation of the ice, and by sliding over the rocks and sediments at the base. Internal deformation occurs when the weight and mass of a glacier causes it to spread out due to gravity. Sliding occurs when the glacier slides on a thin layer of water at the bottom of the glacier.

WebGravity is the cause of glacier motion; the ice slowly flows and deforms (changes) in response to gravity. A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster. WebOct 21, 2024 · The two main ways that glaciers erode the underlying rock are abrasion and plucking. As the thick layer of ice pushes against the underlying rock, it scrapes and polishes the rock surface. As glaciers flow, they scratch the underlying bedrock with all the rocky material they are carrying.
