Correct Answer: Correct answer is: (D) Only (A) & (B).

Difficulty: Moderate

Concept notes: When oceanic and continental crust collide, two primary geological features typically form: deep ocean trenches and volcanoes.

Common Mistakes: Students may overlook the formation of both features, focusing only on one aspect of the collision.

Explanations: When oceanic and continental crust collide, the denser oceanic crust subducts beneath the less dense continental crust. This subduction process creates a deep ocean trench. As the oceanic crust descends into the mantle, it melts due to increased temperature and pressure, forming magma. This magma rises through the continental crust, leading to volcanic activity and the formation of volcanoes. Therefore, both deep ocean trenches and volcanoes are formed as a result of this collision.

Option Analysis:

Option A: A deep ocean trench occurs due to the subduction of the oceanic crust beneath the continental crust.
Option B: Volcanoes form as a result of the magma generated from the subducted oceanic crust rising through the continental crust.
