Chapter 4: Lithosphere – Exogenic Processes — Online MCQ Test

Q: Which of the following is an example of an exogenic process?

Answer: C. Weathering — Weathering is an exogenic process that occurs on the surface of the earth due to external forces.

Q: The process of breaking down of rocks by physical forces is known as:

Answer: B. Physical weathering — Physical weathering involves the disintegration of rocks without any chemical change in the mineral composition.

Q: Which of these is a typical depositional landform created by a river?

Answer: C. Delta — Deltas are formed by the deposition of sediments at the river mouth where the velocity decreases.

Q: If you observe a hanging valley, which agent of erosion is likely responsible?

Answer: B. Glacial ice — Hanging valleys are formed when smaller glacial valleys are left high above the main glacial trough.

Answer: B. Physical weathering
Physical weathering involves the disintegration of rocks without any chemical change in the mineral composition.

Which of these is a typical depositional landform created by a river?

A. Waterfall
B. Gorge
C. Delta ✓
D. Canyon

Answer: C. Delta
Deltas are formed by the deposition of sediments at the river mouth where the velocity decreases.

A. Running water
B. Glacial ice ✓
C. Wind action
D. Groundwater

Answer: B. Glacial ice
Hanging valleys are formed when smaller glacial valleys are left high above the main glacial trough.

Which statement accurately distinguishes 'Solifluction' from 'Debris flow'?

A. Solifluction occurs only in tropical forests.
B. Debris flow involves the slow creep of soil, while Solifluction involves rapid volcanic mud.
C. Solifluction is the slow downslope flow of saturated soil in periglacial regions, while debris flow is more rapid and includes larger fragments. ✓
D. Both are identical processes with different names in different countries.

Answer: C. Solifluction is the slow downslope flow of saturated soil in periglacial regions, while debris flow is more rapid and includes larger fragments.
Solifluction is specific to periglacial freeze-thaw cycles, whereas debris flow is a faster mass movement involving coarse material.
