ANSWER:

Oceanic plates sub duct beneath continental plates because they are more dense.

EXPLANATION:

Our earth is divided into 2 sections of tectonic plates. One is known as the continental plate and the other one is known as oceanic plate. The formation of Oceanic plate is caused due to the divergent of the plate boundaries. In these plates, basaltic lava flows through the volcanic ridge. And in no time its temperatures go down, its turns into igneous rock.
