GENERAL GEOLOGY

Detailed explanation-1: -Oceanic Crust is the thinnest layer of earth.

Detailed explanation-2: -The Earth is covered by two kinds of crust-continental and oceanic. The thinner oceanic crust is normally a little more than four miles thick, while the thicker continental crust is often as much as 25 miles thick. Continental crust is also much less dense than its oceanic counterpart.

Detailed explanation-3: -The term soil refers to the soft, thin layer on the earth’s surface on which plants grow. Soil contains both organic and inorganic substances in large quantity. Soils are generally formed through the breaking down of rocks.

Detailed explanation-4: -There are two main types of crust; continental crust and oceanic crust that differ in a number of ways. Continental crust is thicker than oceanic crust, averaging 20-70 km thick, compared to 5-10 km for oceanic crust.

Detailed explanation-5: -In relation to the other layers the crust is the thinnest and the least dense layer. It floats on the softer, denser mantle. The crust is made up of solid rock but these rocks are not the same all over the world.
