Question

Red sea is an example of a ___________ structure.

• A. Folded
• B. Lava
• C. Faulted
• D. Residual

Answer 1

The correct option is C

Faulted

The correct option is C.

Explanation for correct option:

1. A fault is a planar crack or discontinuity in a mass of rock that has experienced considerable displacement as a result of rock-mass movement.
2. The Red sea is an example of faulted structure.
3. The Red sea is formed due to the discontinuity between the Arabian and African tectonic plates which got highly displaced over the course of time.

Explanation for incorrect options:

Option A:

A fold is a collection of initially flat surfaces, such as sedimentary layers, that have undergone persistent deformation to bend or curve. The Red sea is not a folded structure.

Option B:

Lava is molten rock or liquid that comes out on the earth's surface from the volcano. The Red sea is not an example of a lava structure.

Option D:

Residual structures are the heavy masses that are left behind even after the movement of tectonic plates. The Red sea is not a residual structure.

Final answer: Red sea is an example of a faulted structure.
