Question

Which of the following are examples of Igneous rocks? A. Batholiths B. Stock C. Argillaceous D. Gneiss E. Zeolite

• A. A, B and D only
• B. B, C and D only
• C. A, B, D and E only
• D. A, B and E only

Hint:

Remember that batholiths and stocks are igneous intrusions, while zeolites can form from igneous (volcanic) processes.

Answer 1

The Correct Option is D

Step 1: Concept
Igneous rocks are formed from the cooling and solidification of magma or lava.

Step 2: Meaning
Intrusive igneous bodies form underground; extrusive ones form at the surface.

Step 3: Analysis
Batholiths (A): Large intrusive igneous bodies --- igneous.
Stock (B): Smaller intrusive igneous body --- igneous.
Argillaceous (C): Refers to clay-rich sedimentary rocks --- not igneous.
Gneiss (D): Metamorphic rock --- not igneous.
Zeolite (E): Can form from igneous (volcanic) processes --- related to igneous.

Step 4: Conclusion
Batholiths (A), Stock (B), and Zeolite (E) are associated with igneous processes. Final Answer: (D)
