GEOLOGY

Detailed explanation-1: -Most plates are made of both oceanic and continental crust. An exception is the Pacific plate, which is nearly all oceanic crust. Oceanic crust (basaltic) is thinner and denser than thick and buoyant continental (granitic) crust.

Detailed explanation-2: -The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate.

Detailed explanation-3: -Most tectonic plates are composed of both oceanic and continental crust. The Pacific Plate, however, is made up of mostly oceanic crust.

Detailed explanation-4: -A tectonic plate (also called lithospheric plate) is a massive, irregularly shaped slab of solid rock, generally composed of both continental and oceanic lithosphere. Plate size can vary greatly, from a few hundred to thousands of kilometers across; the Pacific and Antarctic Plates are among the largest.
