The mantle is hotter by a few degrees."The inner core and crust are solid; the outer core and mantle layers are plastic or semi-fluid. The various layers are separated by discontinuities which are evident in SEISMIC DATA; the best known of these is the Mohorovicic discontinuity between the crust and upper mantle."
"The core is probably composed mostly of iron (or nickel/iron) though it is possible that some lighter elements may be present, too. Temperatures at the center of the core may be as high as 7500 K, hotter than the surface of the Sun. The lower mantle is probably mostly silicon, magnesium and oxygen with some iron, calcium and aluminum. The upper mantle is mostly olivene and pyroxene (iron/magnesium silicates), calcium and aluminum. We know most of this only from SEISMIC TECHNIQUES; samples from the upper mantle arrive at the surface as lava from VOLCANOES but the majority of the Earth is inaccessible. The crust is primarily quartz (silicon dioxide) and other silicates like feldspar."

∙ 12y agoYes, the mantle is larger than the core .
The crust is the outermost smallest layers in our earth, the the core is the innermost layer in our earth it is the second largest layer, and finally the mantle is the most largest layer in our earth it is in the middle of the core and the crust.

∙ 14y agoNo. The mantle is the largest of Earth's layers, and is located in the area between the crust and the outer core.

∙ 15y agoThe mantle comprises about 70% of Earth's volume.

Which is denser the inner core or the outer core?
The mantle is more dense than the asthenosphere, lithosphere, and the crust. The inner core and the outer core are more dense, however. The mantle is also a solid. I am learning this in my science class right now! :)
What are denser crustal rocks or mantle?
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.
How is the mantle related to the outer core?
The outer core of the earth is considered to be a liquid. The mantle is considered solid rock, but could be as much as 5% molten. The outer core is mostly iron and nickel, meanwhile the mantle is mostly ultra mafic rock. The outer core is hotter and more dense than the mantle.
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.
How many miles thicker are the outer core and inner core together than the mantle?
The radial thickness of the inner and outer core is equal to 3,486 km (2,166 miles). The mantle is 2,885 km (1,793 miles) thick. As such the inner and outer core combined is 601 km (373 miles) thicker than the mantle.

What is hotter inner mantle or outer mantle?
the earths core is the hottest part of the earth. the metals in the earths outer core is liquid because of the heat and the metals in the earths core is solid but still the earths core is the hottest
What are the 4 layers of the earth from inside to out?
The Earth is comprised of four main layers. Listed in order from outermost to innermost layer, they are: crust, mantle, outer core, inner core.
What are two divisiosn of the earths core?
, a liquid outer core that is much less viscous than the mantle, and a solid inner core.
Why does the earth's crust sit on top of the mantel?
The outer core is composed of molten iron and nickel, which is much denser than the material that composes the mantle. So, in a sense, the mantle floats on top of the core just as the crust floats on top of the mantle.
Ocean crust is denser than the continental crust because it contain more of which 3 element?
It is the crust and mantle,and core
