"A glacier flows slowly due to stresses induced by its weight. The crevasses and other distinguishing features of a glacier are due to its flow. Another consequence of glacier flow is the transport of rock and debris abraded from its substrate and resultant landforms like cirques and moraines."
A cirque is a curved shape that inward like a inner surface of a bowl formed on the head of a valley glacier by erosion (erosion is a wearing away of rock or soil by physical breack down, chemical solution and transportation of materials caused by water, wind or ice.) “A cirque opens on the downhill side corresponding to the flatter area of the stage, while the cupped seating section is generally steep cliff-like slopes down which ice and glaciated debris combine and converge from the three or more higher sides.”
Also, moraines are glacial landforms. "They are long, sharply crested ridges made up of a mixture of sand, gravel, and rocks that have been deposited by a melting glacier. There are many different moraines includes terminal and literal moraines:"
Literal Moraine forms parallel ridges of debris deposited along side of a glacier
Terminal Moraine is also end moraine, which forms at end of the glacier
