Explanation:

Inner core – a ball of hot solid metal at the center of the earth made of iron Outer core – liquid layer of metal nickel & iron that surrounds the inner core Mantle – earth’s thickest layer between the outer core and crust made of magma. This is made of silicate rocks.

This layer is said to be rich in iron and magnesium along with other molten rocks called as magma. There are different temperatures varying the depth as it goes. The upper mantle known as the asthenosphere is 200 km thick containing the heavy weight hard rocks. But the inner mantle is constituted of semi molten rocks that are soft, and they melt.
