Mantle crust is denser. I say this because most likely less dancer things are floating on of dancer things. Is the same thing with the mantle and the crustal rocks.

What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
Which components are much more abundant in mantle rocks than crustal rocks?
Iron and magnesium in particular.
The mantle is denser than the crust because it contains more what?
The mantle contains more iron, making it denser.the mantle contains more magnesium and less aluminum than the crust .this make sthe mantle denser than the crust.
Why do rocks dirt and water separate into layers?
Rocks are denser than dirt, and dirt is denser than water
Why is mantle hotter and denser than the crust?
The mantle is closer to the molten core of earth, so it is constantly heated by it. The crust is exposed to the atmosphere, which has some cooling effect, and the crust is, of course farthest from the core.
What has less density--the crustal rocks or the mantle rocks?
Crustal rock is normally less dense than mantle rock.
What Plates ride or float on the top of the?
The crustal plates (both continental and oceanic) float on the denser mantle.
Which components are much more abundant in mantle rocks than crustal rocks?
Iron and magnesium in particular.
Can the rocks in the crust move around more easily than the rocks in the lower mantle?
No, crustal rock is cold, hard, and brittle while mantle rock is hot, soft, and plastic. Crustal rock fractures under stress while mantle rock deforms and slowly flows under stress.
Why is the lower mantle denser the the upper mantle?
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.
What is crustal Compression?
when they are pushed together they form crustal rocks
Do plates and crustal plates differ?
Plates and Crustal plates are not different it can also be called as Crustal rocks
What layer do the crustal plates float?
The Lower part mantle
What is primary causes of crustal movement?
Convection currents in the mantle.
Where does crustal plates float?
the plates float on top of the upper mantle
How do upper mantle rock differ from lower mantle rock?
the upper-mantle rocks are heavier while the lower mantle rocks are semisolid like melted plastic
What are the characteristics of earths crust mantle core?
The Mantle--The layer directly below the crust which is delineated from the crust by the Mohorovicic Discontinuity, where seismic waves increase in velocity. The division between the mantle and the crust is a chemical one, the rocks and constituent minerals being higher in magnesium and lower in silicon and aluminum than crustal rocks. The mantle comprises 84% of Earth's volume.
