Mantle is Earth’s thickest layer and approximately 3000km in depth. It lies below the crust and surrounds the core. Since the temperature in this part is very high so the mineral matter is still in molten condition.

The outer core lies above the inner core. It is made from iron and nickel but it is a liquid layer which is responsible for Earth’s magnetic field.

This magnetic field acts as a protective shield around the Earth. The inner core also contains nickel and iron. It is too hot, around 5000 degree Celsius which is similar to the surface of sun.

We use this 3% clean water for our basic needs. There are many natural resources on Earth like stone, sand, natural gases, metals oil and coal.
