Earth has three layers: the uppermost crust, the middle mantle and the innermost core. The outer layer of Earth- the crust, can be classified as either continental crust or oceanic crust, depending upon whether it houses the continents or the oceans. The crust is divided into a number of fragments, each known as a tectonic plate. These plates are in constant motion.

Oceanic and continental plates commonly meet at convergent margins or boundaries. Oceanic plates are generally denser as compared to continental plates and slide under the lighter continental plates. This process is known as subduction. Since continental plates are lighter as compared to the oceanic plates, they are more buoyant. Continental plates are also older as compared to the oceanic plates. Another difference is the thickness of these plates. Continental plates are generally thicker as compared to the oceanic plates.
