How do glaciers impact the topography of an area?
Glacial Erosion Glaciers can shape landscapes through erosion, or the removal of rock and sediment. They can erode bedrock by two different processes: Abrasion: The ice at the bottom of a glacier is not clean but usually has bits of rock, sediment, and debris. It is rough, like sandpaper.
How do alpine glaciers change the mountain landscape over time?
Alpine glaciers pluck and grind up rocks creating distinctive U-shaped valleys and sharp mountain peaks and ridges. Valley glaciers erode V-shaped stream valleys into much more rounded or U-shaped valleys.
What features can an Alpine glacier create?
LANDFORMS MADE BY ALPINE GLACIERS Figure 17.7 shows how alpine glaciers erode mountain masses to create landforms such as aretes, horns, cols, moraines, tarns, hanging valleys, and glacial troughs.
Which type of glacier is affected by topography?
Icefields. Icefields are similar to ice caps, except that their flow is influenced by the underlying topography, and they are typically smaller than ice caps.
How is Arete formed?
An arête is a knife-edge ridge . It is formed when two neighbouring corries run back to back. As each glacier erodes either side of the ridge, the edge becomes steeper and the ridge becomes narrower. A pyramidal peak is formed where three or more corries and arêtes meet.
