FAQs on IIT JAM GEOLOGY - GG - Free coaching Lecture 16 - Geologic work of Glacier; In English
| 1. What is the significance of glaciers in geological processes? |  |
Ans. Glaciers play a crucial role in geological processes by shaping landscapes through erosion and deposition. They carve valleys, create fjords, and transport sediment over long distances, which contributes to soil formation and landscape evolution.
| 2. How do glaciers erode the landscape? | |
Ans. Glaciers erode the landscape primarily through processes such as plucking and abrasion. Plucking involves the glacier freezing onto rocks and pulling them away as it moves, while abrasion occurs as the glacier grinds against the bedrock, smoothing and polishing surfaces.
| 3. What types of landforms are created by glacial activity? | |
Ans. Glacial activity creates a variety of landforms, including U-shaped valleys, cirques, aretes, and moraines. U-shaped valleys are formed by the erosive action of glaciers, while moraines are accumulations of debris deposited by glaciers at their edges.
| 4. What is the process of glacial deposition? | |
Ans. Glacial deposition occurs when a glacier loses energy and can no longer transport its load of sediment. This results in the deposition of materials such as rocks, gravel, and clay, forming features like drumlins and terminal moraines, which provide insights into past glacial movements.
| 5. How do glaciers impact climate and ecosystems? | |
Ans. Glaciers significantly impact climate and ecosystems by regulating water supply and influencing local weather patterns. As glaciers melt, they contribute to freshwater resources for rivers and lakes, and their presence can also affect temperatures and precipitation patterns in surrounding areas.
