Which landform results from a reverse fault?

• A. Volcanic island
• B. Oceanic trench
• C. Plateau
• D. Escarpment

Answer: (B)

The correct answer is that a landform resulting from a reverse fault is an escarpment.

A reverse fault occurs when the forces in the Earth's crust compress the rock layers, causing one side of the fault to be pushed up over the other. This movement can lead to the formation of prominent features, such as escarpments, which are steep cliffs or slopes that form along the edge of a plateau or other landform. The nature of reverse faulting creates an upward thrust, contributing to the dramatic changes in elevation associated with escarpments.

In contrast, volcanic islands and oceanic trenches are formed by different geological processes, such as plate tectonics and volcanic activity. Plateaus, while they can be influenced by faulting, are typically formed by processes such as erosion or volcanic activity without the specific movement associated with reverse faults. Thus, escarpments are directly linked to the geological activity typical of reverse faults.
