Solution:
1. Inner Core: It is the center and the hottest layer of the Earth. The inner core is solid and made up of iron and nickel.
2. Outer Core: The outer core of the Earth is similar to a very hot ball of metals. It is composed of metals such as iron and nickel. The outer core surrounds the inner core.
3. Mantle: Mantle is the widest section of the Earth. Mantle is mainly made up of semi molten rock known as magma. The rock is hard in the upper part of the mantle, but lower down the rock is softer and begins to melt. The mantle consists of very hot and dense rock.
4. Crust: The crust is the outer layer where we live. It’s a solid rock layer divided into two types: Continental crust covers the land and Oceanic crust covers water.
