Steep-sided peaks, shaped like pyramids, formed when cirque glaciers erode on three or more sides of a mountain. Tarn. A small lake filling a hollow which was eroded out by ice or dammed by a moraine. Frequently found with cirques.
The rock is then plucked out and carried away by the flowing ice of the moving glacier (Figure below). Glaciers are the "river of ice" that too erode the landscape by bulldozing soils and stones to expose the solid rocks from below. A beautiful lake in the mountains is created when the ice melts. Masses of moving ice can be two types: Moving as sheet called continental or piedmont of the glacier. Owing to the force applied by the weight of the ice, the glaciers move very slowly almost 2 cm per day.
A recent study challenged the assumption that cold glaciers neither slide nor abrade their beds, but no geological evidence was offered. The features we describe include abrasion marks, subglacial deposits, glaciotectonically deformed substrate, isolated blocks, ice-cored debris mounds, and Glaciers erode landscapes by: A)lithification B)solution C)saltation D)abrasion.

How do glaciers erode? When gravity causes ice to move down the side of a mountain there are two ways in which the rock below is eroded. These are plucking and abrasion. Freeze-thaw weathering is a process that also affects glacial environments.
This is known as glacial erosion. Simply put, glacial erosion is the curving and shaping of the land beneath a moving glacier. Answer: Glaciers erode land through Plucking and Abrasion. Glaciers are mass form of ice found in the high altitudes.
