SSC MTS EXAM

Detailed explanation-1: -Each layer has a unique density (density = mass/volume). Scientists believe that all planets formed on the basis of gravity. Therefore, the layering of Earth is a result of gravitational pull. The densest layer (inner core) is at the center and the least dense layer (crust) is the outermost layer.

Detailed explanation-2: -Inner Core. The inner core is the deepest layer on Earth. It is also made up of iron and nickel but the pressure is so high that it is no longer liquid.

Detailed explanation-3: -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.
