Question

Match the features in Group I with their characteristic rocks / rock suite in Group II. 

 

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

Hint:

Understanding geological features and the associated rock types is crucial in interpreting tectonic environments and their processes.

Answer 1

The Correct Option is C

Step 1: Understanding the Features and Rock Suites.
- Continental arcs are associated with olivine tholeiite (P-1).
- Mid-oceanic ridges are characterized by andesite (Q-3).
- Collision zones are associated with ophiolite (R-4).
- Continental rifts are associated with alkaline rocks (S-2).
Step 2: Analyzing the options.
(A) P-2, Q-3, R-4, S-1: Incorrect — The match for continental arcs is incorrect.
(B) P-3, Q-4, R-1, S-2: Incorrect — The match for collision zones is incorrect.
(C) P-1, Q-3, R-4, S-2: Correct — This correctly matches the features with their rock suites.
(D) P-4, Q-2, R-3, S-1: Incorrect — The matches for all features are incorrect.
Step 3: Conclusion.
The correct answer is (C) P-1, Q-3, R-4, S-2, as it correctly matches the features with their characteristic rocks or rock suites.
