The geological process where one tectonic plate is forced beneath another plate into the Earth’s mantle, often resulting in deep ocean trenches and volcanic arcs, is known as what?

💡 Explanation:

Subduction occurs at convergent plate boundaries, where denser oceanic crust typically slides beneath less dense continental or oceanic crust. This process is responsible for forming the deepest parts of the oceans (trenches) and triggering significant volcanic and seismic activity.
