FAQs on GC Leong: Landforms of Glaciation Video Lecture - Geography for UPSC CSE

1. What are landforms of glaciation?
Ans. Landforms of glaciation are geological features that are created by the movement and melting of glaciers. These include features such as U-shaped valleys, cirques, moraines, and drumlins. Glaciers erode the landscape as they move, carving out these distinct landforms.
2. How are U-shaped valleys formed by glaciation?
Ans. U-shaped valleys are formed by the erosive power of glaciers. As glaciers move down a valley, they gradually scrape and erode the sides and bottom of the valley. This continuous erosion results in the formation of a wide, U-shaped valley with steep sides and a flat bottom.
3. What is a cirque and how does it form during glaciation?
Ans. A cirque is a bowl-shaped depression formed at the head of a glacier. It is created through a combination of erosion and plucking. As a glacier moves downhill, it erodes the surrounding rock, creating a steep-walled hollow depression. Snow and ice accumulate in this depression, forming a bowl-like shape.
4. How are moraines created during glaciation?
Ans. Moraines are created by the deposition of rock and sediment carried by glaciers. As glaciers move, they pick up rocks and debris from the surrounding landscape. When the glacier eventually melts, it deposits this material in the form of a ridge or mound, known as a moraine. Moraines can be found along the sides, front, or within a glacier.
5. What is a drumlin and how does it form as a landform of glaciation?
Ans. A drumlin is a smooth, elongated hill or mound that is formed by the movement of glaciers. It is typically composed of glacial till, a mixture of rocks, sand, and clay. Drumlins are created when glaciers deposit and reshape sediment in a streamlined fashion. These elongated landforms can give clues about the direction of glacier movement during the ice age.
