INDIAN GEOGRAPHY

Detailed explanation-1: -Earth’s crust is divided into two types: oceanic crust and continental crust. The transition zone between these two types of crust is sometimes called the Conrad discontinuity. Silicates (mostly compounds made of silicon and oxygen) are the most abundant rocks and minerals in both oceanic and continental crust.

Detailed explanation-2: -Earth’s crust is divided into two main types. They are the oceanic crust and the continental crust. Oceanic crust: Oceanic crust extends 5-10 kilometres beneath the ocean floor. It is mostly composed of different types of basalts.

Detailed explanation-3: -Summary. Oceanic crust is thinner and denser than continental crust. Oceanic crust is more mafic, continental crust is more felsic. Crust is very thin relative to Earth’s radius.

Detailed explanation-4: -Oceanic plates are plates that lie primarily under the ocean. Continental plates are those containing continents. As the plates interact with each other like when two continents collide together, they shape the topography, or relief, of the Earth’s surface.
