GEOLOGY

Detailed explanation-1: -The location where sinking of a plate occurs is called a subduction zone. The type of convergence–called by some a very slow “collision”–that takes place between plates depends on the kind of lithosphere involved.

Detailed explanation-2: -Subduction zones are where subduction takes place. Subduction of an oceanic plate beneath a continental plate forms a line of volcanoes known as a continental arc and causes earthquakes.

Detailed explanation-3: -Subduction zones are where the cold oceanic lithosphere sinks back into the mantle and is recycled. They are found at convergent plate boundaries, where the oceanic lithosphere of one plate converges with the less dense lithosphere of another plate.

Detailed explanation-4: -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-5: -At an ocean-ocean convergent boundary, one of the plates (oceanic crust and lithospheric mantle) is pushed, or subducted, under the other (Figure 4.6. 1).
