What characteristics of continental crust allow it to float higher on the mantle than oceanic cruast?
Continental crust is less dense than oceanic crust.
Is earths mantle hotter or cooler than the crust?
The mantle is hotter than the crust.
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.
What is the crust of the earth's interior made of?
The Earth's crust is on the exterior, not the interior; that is why it is called the crust. It is on the outside. It is made mostly of rock, of various kinds. The rock of the crust is on average less dense than the rock of the mantle, which lies beneath the crust.
What is thought to be common in the Earth's mantle but rare in the crust?
Peridotite is thought to be the dominant rock in the upper portions of the mantle. It's ultramafic, meaning it contains less than 45% silica.
The mantle has less aluminum and less?
The mantle has less aluminum and silicon than the crust does.
The mantle has less aluminum and less than the crust does.?
silicon
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 does Earth's crust sit on top of the mantle?
The crust lies on top of the mantle because it is composed of less dense materials than the mantle is. The crust is essentially floating on the mantle.
The crust floats on the mantle because?
the crust(~2.7g/cm3) is less dense than the mantle(~3.3 g/cm3)
Why doesnt the crust fall into the mantle and burn up?
the crust is lighter and less dense than the mantle...thus it floats on top.
What characteristics of continental crust allow it to float higher on the mantle than oceanic cruast?
Continental crust is less dense than oceanic crust.
How dense is the continental crust?
less dense than the material of the Earth's mantle
Why would a certain thickness of continental crust displace less of the mantle than the same thickness of oceanic crust?
Because its less dense
Is the mantle thicker or thinner than the crust?
The crust is much thinner than the mantle.
Is earths mantle hotter or cooler than the crust?
The mantle is hotter than the crust.
Is the crust thinner or thicker than the mantle?
The crust is much thinner than the mantle.
