Describe oceanic-continental convergence.

• A. A process where oceanic plates drift apart
• B. A type of divergent boundary leading to new crust
• C. A type of convergent boundary where an oceanic plate subducts beneath a continental plate
• D. A boundary where two oceanic plates collide

Answer: (C)

Oceanic-continental convergence is characterized by a type of convergent boundary where an oceanic plate subducts beneath a continental plate. This occurs because oceanic crust is denser than continental crust. As the oceanic plate moves toward the continental plate, it is forced downward into the mantle, creating a subduction zone. This process leads to significant geological features and events, such as the formation of mountain ranges on the continent, deep ocean trenches, and volcanic activity. The intense pressure and friction during this subduction process can also trigger earthquakes. Understanding this mechanism is crucial in recognizing how the Earth’s tectonic activities shape its landscape and influence geological hazards.
