Q. Abrasion
R. Deposition
S. Onion skin weathering
Group II
1. Mushroom rocks
2. Exfoliation domes
3. Sinkholes
4. Moraines

• A. P-1, Q-3, R-2, S-4
• B. P-3, Q-1, R-2, S-4
• C. P-3, Q-1, R-4, S-2
• D. P-2, Q-1, R-4, S-3

Hint:

Dissolution, abrasion, and deposition are key geological processes responsible for various geomorphic features such as sinkholes, mushroom rocks, and moraines.

Answer 1

The Correct Option is C

To solve this problem, we need to correctly match the processes listed in Group I with the geomorphic features in Group II based on geological knowledge.

1. Dissolution (P): Dissolution is a process of chemical weathering where soluble minerals in rocks, like limestone, are dissolved by acidic water, often leading to the formation of sinkholes. Therefore, we match P-3.
2. Abrasion (Q): Abrasion is a physical weathering process caused by friction and impact of particles carried by wind or water, often leading to the formation of unique erosional features such as mushroom rocks. Thus, we pair Q-1.
3. Deposition (R): This is a geological process where sediments are laid down primarily by wind, water, and ice. It results in the formation of accumulative structures such as moraines, which are ridges of debris deposited by glaciers. Hence, we associate R-4.
4. Onion skin weathering (S): Also known as exfoliation, this process involves layers pealing from rocks due to thermal expansion and contraction. This leads to the formation of exfoliation domes. Therefore, S corresponds to 2, or S-2.

By systematically matching each process with its corresponding geomorphic feature, we determine that the correct answer is:

P-3, Q-1, R-4, S-2
