Distinguish between Core and mantle.

1.	Distinguish between Core and mantle.
Answer» The Mantle\tThe portion of the interior beyond the crust is called the mantle.\tIt is in a solid state.\tIt has a density higher than the crust portion.\tThe thickness ranges from 10-200 km.\tThe mantle extends from Moho’s discontinuity to a depth of 2,900 km.\tThe asthenosphere is the upper portion of Mantle.\tIt is the chief source of magma that finds its way to the surface during volcanic eruptions.\tThe crust and the uppermost part of the mantle are called lithosphere.\tThe major constituent elements of the mantle are Silicon and Magnesium and hence it is also termed as SIMA\xa0The Core\tThe core-mantle boundary is positioned at the depth of 2,900 km.\tThe inner core is in the solid state whereas the outer core is in the liquid state.\tThe core is made up of very heavy material mostly constituted by nickel and iron. Hence it is also called the “nife” layer.
