The outer layer of the Earth is called the crust. It is a thin layer and it is composed of rocks. The crust is further divided into two types: oceanic crust and continental crust.
The Mantle
It is a solid and rocky layer. The mantle layer is so huge that it consists more than 82 percent of the entire volume of the Earth. The thickness of the mantle layer is almost 2,900 kilometers. The mantle is made up of two portions; upper mantle and lower mantle
The Core
The core is made up of iron and nickel alloys. In addition to these, there are some other elements that react with iron very quickly and develop into different compounds. These small amounts of elements are sulfur, oxygen and silicon. There is a great pressure inside the core. The core is further divided into two different parts: Outer Core and Inner Core.
