Subduction of oceanic plates under continental plates occurs at convergent plate boundaries, where the plates are moving toward each other. When an oceanic plate meets a continental plate, it is usually the one subducted, due to its greater density.
The Pacific "Ring of Fire", particularly east to south East Asia and the west coast of South America, is the result of oceanic plate subduction, and hence there is a high number of earthquakes and volcanism in the area.

Continental Drift happened, when the tectonic plates in the earth shifted, and pushed the lithosphere up, causing our continents to split.
The collision of plates commonly includes "subduction", where one plate is forced under the other, down into the mantle. These plates are melted and rise again, adding to the magma under the overlying plate. This creates heated rock that can later emerge through the surface in volcanoes. Oceanic plates are thinner and denser than continental plates, so are the ones forced down, either under a continental plate or another oceanic plate.
The driving Forces of Continental drift are both gravity and the motion of the underground Tectonic Plates.
The edge of the oceanic and continental plates.
Subduction zones are where the seafloor is forced under continental plates.
The region where the seafloor is forced beneath the continental plate is called a subduction zone. When the seafloor descends down it produces a deep-ocean trench.

Seafloor continues to move away from the mid-ocean ridge and eventually comes into contact with another plate boundary. Ocean plates subduct underneath continental plates and are forced down into the lithosphere
Continental plates are massively granitic rock, oceanic plates massively basaltic rock, therefore continental rock is less dense than seafloor rock and has a different chemical and mineralogical composition.
Contintal plates
Seafloor spreading is caused by two plates moving apart. This is caused by plate tectonics. Continental drift is also caused by plate tectonics. Therefore, we can conclude that continental drift is related to seafloor spreading. When the plates move, it carries the continents with it, and thus the continents drift away from each other.
Deep-ocean trenches are formed where seafloor tectonic plates subduct under continental plates.
Yes. Seafloor spreading is the term given to the creation of new seafloor at divergent boundaries. At a divergent boundary, two oceanic plates move apart, which obviously means that something must then surface to fill the void. This is where the magma rises from the Earth's interior and cools to become seafloor. On the other end, at convergent boundaries, the old seafloor is forced under the continental plates, where it is recycled back into the Earth's magma supply.
