<em>Continental plate is less denser than the oceanic plate so it is floating on the oceanic plate. </em>
<u>Explanation:</u>
Continental plate is composed of Silicon and Aluminiummaterials otherwise it is known as SiAl layer, its averagedensity is 3 g/m3. Oceanicplate is composed of Silicon and Magnesium minerals otherwise it is known as SiMa layer and its averagedensity is 5 g/cm3. Both continent and ocean plate lies in the Lithospehere, it extends up to 100 km of the below earth. Temperature will increase if we go beyond every metre in depth.
