Matching Geological Features: Columns I and II

This question requires matching geological features from Column I with their correct descriptions or locations in Column II.

Column I Item Analysis:

• A. Mid Atlantic Ridge: This is a major underwater mountain range. Its extensive path runs from the Arctic region southwards through the Atlantic Ocean.
• B. Rodriguez Triple Junction: Located in the Indian Ocean, this is a significant point where tectonic plates meet.
• C. $90^\circ\text{E}$ Ridge in the Indian Ocean: This specific ridge is known for its lack of seismic activity.
• D. Macquarie Triple Junction: This is a specific junction where three major tectonic plates converge.

Column II Description Analysis:

• P. is in the central Indian Ocean: Describes a location, fitting for the Rodriguez triple junction.
• Q. is the junction of Indo-Australian, Pacific , and Antarctic Plates: Describes a specific type of plate boundary convergence, characteristic of the Macquarie triple junction.
• R. extends from the Ice land in north to Bouvet triple junction in the south: Describes the extensive geographical extent of a major ridge system, fitting the Mid Atlantic Ridge.
• S. is an aseismic ridge: Describes a physical characteristic (lack of earthquakes), fitting the $90^\circ\text{E}$ ridge.

Correct Matching:

Based on the analysis:

• A. Mid Atlantic Ridge matches with R. (its extensive path).
• B. Rodriguez Triple Junction matches with P. (its location in the central Indian Ocean).
• C. $90^\circ\text{E}$ Ridge matches with S. (being an aseismic ridge).
• D. Macquarie Triple Junction matches with Q. (the specific plates involved).

Therefore, the correct matching is A - R, B - P, C - S, D - Q.
