Question

Each layer of the earth has a unique chemical composition, physical state, and can

impact life on Earth’s surface. In the light of above mention statement answer the

following question.

On the basis of chemical composition of the earth differentiate between continental

crust and oceanic crust​

Answer 1

Answer:

The structure of the earth is divided into four major components: the crust, the mantle, the outer core, and the inner core. Each layer has a unique chemical composition, physical state, and can impact life on Earth's surface.

Answer 2

Answer:

Continental crust is broadly granitic in composition and, with a density of about 2.7 grams per cubic cm, is somewhat lighter than oceanic crust, which is basaltic (i.e., richer in iron and magnesium than granite) in composition and has a density of about 2.9 to 3 grams per cubic cm.
