Glacial Movement
Mountain glaciers are large terrestrial ice formations in the mountains. Their shape depends on the surrounding terrain, and the movement is determined by the inclination of the surface. The move is acceleration-based, where the increase in speed can be seen. The overall pace is affected only by the obstacles of the slope and steepness degree. If the slope possesses a large number of protrusions, it will slow down the glacial progression downwards. In reality, the movement of the glacier is determined by the mass and steepness of the hill or mountain. The relative speed can range from 2 meters up to 70 meters per day. The movement occurs mostly by sliding, but it is important to note that upper layers dislocate at a faster pace than lower ones.
Glacial Erosion
There are three critical categories of glacial erosion, such as freeze-thaw, plucking, and abrasion. Freeze-thaw is the process that occurs when the water flows into the cracks of the rocks. The rocks undergo severe erosion because water expands when it turns into ice. This volume increase leads to more cracks in the bedrock, which allows more water gets in. The appearance includes stripes of erosion alongside the ice deposits.
Glacial Deposits
The main glacial depositional features include moraines, which are precipitations of the concentrated till of various landforms. The appearance is a layered structure with colors ranging from dark brown to bright pale. The moraines are formed by continuous till accumulations and erosional washouts. Both glacial erosional and depositional features are essential elements of the icy structural build-up alongside its general movement. The resulting formation is a summation of the consequences influenced by the given factors.
