GENERAL KNOWLEDGE

Detailed explanation-1: -In geology, continental collision is a phenomenon of plate tectonics that occurs at convergent boundaries . Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together.

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: -Where do subduction zones typically occur? Subduction zones occur in a horseshoe shape around the edge of the Pacific Ocean, offshore of Washington state, Canada, Alaska, Russia, Japan and Indonesia and down to New Zealand and the southern edge of South America, according to NOAA (opens in new tab).
