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. WebSep 23, 2024 · There are two main processes of glacial erosion. The first that we will talk about is plucking, which is defined as the erosion and transport of large chunks of rocks. As a glacier moves over... WebJul 16, 2024 · 1. In a sense, Antarctica is already separated with a mountain range down the middle.

WebMay 20, 2024 · When a glacier does move, it is often downhill due to gravity. As the glacier slides over Earth’s surface, it erodes its surface by polishing bedrock, pushing soil, … 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.

WebGlaciers move very slowly. As they move, they transport material from one place to another: As freeze-thaw weathering occurs along the edge of the glacier pieces of rock, which … 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.

WebDec 13, 2024 · Glaciers can move by internal plastic deformation, where the glacier's weight causes its lower levels to move and flow differently than the upper layers. They can also … 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 …
