Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
the process in which a denser plate is pushed downward beneath a less dense plate when plates converge; occurs at continental to oceanic boundaries and oceanic to oceanic boundaries
A
divergent boundaries
B
volcanic eruptions
C
subduction
D
convergent boundary
Explanation: 

Detailed explanation-1: -As the plates collide, the denser plate will sink beneath the other plate, producing a subduction zone. This process is known as subduction. As the oceanic plate is pushed deeper into the mantle, volcanoes and mountain ranges may form.

Detailed explanation-2: -Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth’s mantle.

Detailed explanation-3: -This process is called subduction. A deep ocean trench forms at this subduction boundary. As the subducting plate plunges deep into the mantle, it gets so hot it melts the surrounding rock. The molten rock rises through the crust and erupts at the surface of the overriding 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.
