Detailed explanation-1: -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.
Detailed explanation-2: -Inner Core. The inner core is the deepest layer on Earth.
Detailed explanation-3: -The inner core’s intense pressure-the entire rest of the planet and its atmosphere-prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.
Detailed explanation-4: -The Four Layers Many geologists believe that as the Earth cooled the heavier, denser materials sank to the center and the lighter materials rose to the top. Because of this, the crust is made of the lightest materials (rock-basalts and granites) and the core consists of heavy metals (nickel and iron).
