Detailed explanation-1: -Convergent (Colliding): This occurs when plates move towards each other and collide. When a continental plate meets an oceanic plate, the thinner, denser, and more flexible oceanic plate sinks beneath the thicker, more rigid continental plate. This is called subduction.
Detailed explanation-2: -Convergent boundaries, where two plates are moving toward each other, are of three types, depending on the type of crust present on either side of the boundary-oceanic or continental . The types are ocean-ocean, ocean-continent, and continent-continent.
Detailed explanation-3: -Convergent boundaries can form mountains, volcanos, or subduction zones that form large trenches. When two plates collide, the crusts can push together to form mountain ranges. This is how the Himalayan mountains were formed. Convergent boundaries between oceanic and continental boundaries feature a subduction zone.
Detailed explanation-4: -Convergent boundary movement is divided into two types, subduction and collision, depending on the density of the involved plates. Continental lithosphere is of lower density and thus more buoyant than the underlying asthenosphere.
Detailed explanation-5: -Divergent boundaries–where new crust is generated as the plates pull away from each other. Convergent boundaries–where crust is destroyed as one plate dives under another.
