SOLAR SYSTEM

Detailed explanation-1: -When oceanic crust collides with a continent, an oceanic-continental convergent boundary forms. The oceanic plate is denser, so it undergoes subduction. This means that the oceanic plate sinks beneath the continent, forming a deep ocean trench.

Detailed explanation-2: -A subduction zone is a region in which a portion of a tectonic plate sinks beneath another plate into the Earth’s interior. Subduction zones are defined by deep oceanic trenches, lines of volcanoes parallel to the trenches, and zones of large earthquakes that extend from the trenches landward.

Detailed explanation-3: -Volcanoes at convergent plate boundaries are found all along the Pacific Ocean basin, primarily at the edges of the Pacific, Cocos, and Nazca plates. Trenches mark subduction zones. The Cascades are a chain of volcanoes at a convergent boundary where an oceanic plate is subducting beneath a continental plate.

Detailed explanation-4: -Convergent Plate Boundary Development 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).
