What are convergent plate boundaries ?

Convergent Plate Boundary Development

Subduction

Where tectonic plates converge, the one with thin oceanic crust subducts beneath the one capped by thick continental crust. A subduction zone consists of material scraped off the ocean floor near the coast (accretionary wedge) and a chain of volcanoes farther inland (volcanic arc).

Terran Accretion

Oceanic islands and continental fragments approaching the subduction zone are too thick and buoyant to subduct. Instead, they attach to the edge of the continent as accreted terranes.

Continental Collision

Continents collide where subduction completely closes an ocean. The buoyant continental crust lifts up a broad region known as a collision mountain range.
