write important three section of the earth
Answers
Answer: Earth can be divided into three main layers: the core, the mantle and the crust. Each of these layers can be further divided into two parts: the inner and outer core, the upper and lower mantle and the continental and oceanic crust. Both the inner and outer core are made up of mostly iron and a little bit of nickel.
Explanation: crust:The crust is the outermost layer of the Earth. It is made of solid rocks. It is mostly made of the lighter elements, silicon, oxygen, aluminium.
MANTLE:The mantle is the layer of the Earth right below the crust. It is made mostly of oxygen, silicon and the heavier element magnesium.
CORE :The Earth's core is made of solid iron and nickel, and is at about 5000–6000 °C.
Outer core is a liquid layer below the mantle.
Inner core is the very center of the Earth.[1]
