WebSubduction zones are plate tectonic boundaries where two plates converge, and one plate is thrust beneath the other. This process results in geohazards, such as earthquakes and volcanoes. These hazards affect millions of people around the world, particularly around the edges of the Pacific Ocean, which mainly consist of subduction zones. WebAs the subduction zone and its associated trench pull backward, the overriding plate is stretched, thinning the crust and forming a back-arc basin. In some cases, extension is triggered by the entrance of a buoyant … WebDefinition: Oceanic tectonic plates are very dense while continental tectonic plates have a much lower density. Where oceanic tectonic plates meet continental tectonic plates, subduction can happen, which is when one plate moves underneath the other plate. Subduction is what happens at a destructive plate boundary. free timber frame barn plans
