Which part of the mantle is similar to the crust ? (science earth's layers)

The mantle is much different from the crust, so I wouldn't think there would be any similarities.

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
