Question

Match the metamorphic rocks in Group I with corresponding parent rocks in Group II. 

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

Hint:

Understanding the parent rocks of metamorphic rocks helps identify their formation conditions and characteristics.

Answer 1

The Correct Option is B

Step 1: Understanding Parent Rocks.
- Amphibolite forms from basalt, hence P-4.
- Khondalite forms from shale, hence Q-2.
- Calc-gneiss forms from limestone, hence R-1.
- Quartzite forms from sandstone, hence S-3.
Step 2: Analyzing the options.
(A) P-4, Q-2, R-1, S-3: Correct — This matches the metamorphic rocks with their parent rocks.
(B) P-2, Q-4, R-1, S-3: Incorrect — The parent rock for Khondalite is shale, not the one in this option.
(C) P-2, Q-1, R-3, S-4: Incorrect — The parent rocks for Amphibolite and Quartzite are not matched correctly.
(D) P-4, Q-3, R-2, S-1: Incorrect — The parent rocks for all minerals are mismatched.
Step 3: Conclusion.
The correct answer is (A) P-4, Q-2, R-1, S-3, as it correctly matches the metamorphic rocks with their parent rocks.
