Match the following geological features (List I) with the primary type of tectonic plate boundary responsible for their formation (List II):
| List I (Geological Feature) | List II (Plate Boundary Type) |
| I. Mid-ocean ridge | 1. Transform Boundary |
| II. Mariana Trench | 2. Convergent Boundary |
| III. San Andreas Fault | 3. Divergent Boundary |
Show answer & explanation
Correct answer: B
Explanation
The correct answer is option 2 i.e. I-3, II-2, III-1.
The correct matching is: I–3, II–2, III–1. A mid-ocean ridge (I) forms at a divergent boundary (3) where tectonic plates move apart, allowing magma to rise and create new oceanic crust. The Mid-Atlantic Ridge is a famous example. The Mariana Trench (II) corresponds to a convergent boundary (2), specifically an oceanic–oceanic subduction zone where one plate sinks beneath another, forming the world’s deepest trench. The San Andreas Fault (III) represents a transform boundary (1), where the Pacific and North American plates slide horizontally past each other, causing frequent earthquakes.
