What geological feature is primarily formed as a result of oceanic-continental convergence?

• A. Trench
• B. Mid-ocean ridge
• C. Mountain range
• D. Volcanic island arc

Answer: (C)

The geological feature primarily formed as a result of oceanic-continental convergence is a mountain range. When an oceanic plate converges with a continental plate, the denser oceanic plate is subducted beneath the continental plate. This subduction leads to significant geological activity, including the melting of the subducted oceanic plate and subsequent magma formation. As this magma rises towards the surface, it can lead to the formation of mountain ranges on the continental plate.

This process often results in volcanic activity in the vicinity of the converging plates, contributing to the formation of chain-like mountain ranges along the continental edge. These mountain ranges are typically characterized by extensive volcanic activity and the uplifting of crustal material due to tectonic forces, making them a defining feature of regions where oceanic and continental plates converge.
