FAQs on Erosional Landforms: Glacial, Marine & Arid Landforms Video Lecture - Humanities/Arts

1. What are some examples of glacial erosional landforms?
Ans. Some examples of glacial erosional landforms include U-shaped valleys, cirques, horns, aretes, and glacial striations.
2. How are marine erosional landforms formed?
Ans. Marine erosional landforms are formed through the action of waves, tides, and currents. These forces can erode coastlines, forming features such as sea cliffs, sea stacks, and wave-cut platforms.
3. What are some examples of arid erosional landforms?
Ans. Examples of arid erosional landforms include mesas, buttes, canyons, arches, and hoodoos. These landforms are shaped by the erosion caused by wind and sporadic rainfall in arid regions.
4. How do glaciers erode the landscape?
Ans. Glaciers erode the landscape through the processes of plucking and abrasion. Plucking occurs when the glacier freezes onto rocks and pulls them away, while abrasion happens when the glacier's movement scrapes against the underlying rocks, wearing them down.
5. What factors contribute to the formation of erosional landforms in marine environments?
Ans. Factors such as wave energy, sediment composition, and coastal geology contribute to the formation of erosional landforms in marine environments. The strength and frequency of waves, as well as the type of sediment and underlying rock, can determine the shape and development of features like cliffs, caves, and sea arches.
