Structure of Earth
The Earth is structured in three layers namely − Crust, Mantle, and Core – Further classified as outer core (fluid layer) and inner core (solid layer).
crust
-
-
• The thickness of Continental Crust ranges from 30 km to 50 km. It is largely composed by granites, which density (i.e. 2.7) is lesser than the Oceanic Crust.
• The thickness of Oceanic Crust ranges from 5 km to 10 km and it is composed primarily of basalt, diabase, and gabbro.
-
• The most abundant element of Crust is Oxygen (46.6%) followed by Silicon (27.7%) and Aluminum (8.1%). :

• The Mantle is located between the Crust and the (Outer) Core, which thickness is about 2885 km.
• The Crust is the uppermost layer of the Earth, largely composed of rocks. Its thickness ranges from 5 km to 60 km and density ranges from 2.7 to 3.
• The Mantle is located between the Crust and the (Outer) Core, which thickness is about 2885 km.
core
• The Core is mostly composed of iron and nickel; therefore, it is also known as ‘Nife’ (i.e. Nickel and Ferrous).
-
• The thickness of the Core is about 3,400 km from the Mantle (likewise, the total depth from the Surface of the Earth is 6,300 km).
• Core is categorized as outer core (which is in molten state) and inner core (which is in solid state).
