Match the following tectonic settings in Group-I with the corresponding examples in Group-II
Show Hint
In tectonic settings, a rift basin is characterized by plate divergence (Gulf of Suez), passive margins are stable continental edges (West coast of India), subducting oceans occur at convergent boundaries (Pacific Ocean), and collisions result in mountain-building (Mediterranean Sea).
Let’s analyze the tectonic settings in Group-I and match them with the correct examples in Group-II.
- P. Rift Basin: A rift basin is typically formed in a region where tectonic plates are pulling apart, causing the formation of valleys and basins. The Gulf of Suez is an example of a rift basin, formed by the tectonic stretching and divergence of the African and Arabian plates. Thus, P → 2.
- Q. Passive Margin: A passive margin is a tectonically stable area where there is no active plate boundary. The West coast of India is an example of a passive margin, as it lies on the stable Indian plate, away from any active tectonic boundaries. Thus, Q → 3.
- R. Subducting Ocean: A subducting ocean setting occurs when one tectonic plate is forced beneath another at a convergent boundary. The Pacific Ocean is a classic example of a subducting ocean setting, as it is associated with subduction zones along the Pacific Ring of Fire. Thus, R → 1.
- S. Collision: A collision setting occurs when two continental plates collide, causing mountain building and tectonic compression. The Mediterranean Sea is an example of a collision zone, formed by the collision of the African and Eurasian plates. Thus, S → 4.
Therefore, the correct answer is (A) P-2; Q-3; R-1; S-4.
