The mantle is hotter and denser than the crust because it is closer to the Earth's core, where temperatures are higher. The mantle is predominantly made up of more dense materials such as silicate minerals, while the crust is composed of lighter materials like granite and basalt. As a result, the mantle undergoes convection currents that drive plate tectonics and geological processes.
Because when the earth was made all of the elements that had larger density's went towards the center, so the crust is thinner than the mantle because of the density.
The lower mantle is under greater pressure than the upper mantle, compressing the rock into a denser form.

The mantle is denser than the crust because it contains more what?
The mantle is denser than the crust because it contains more iron and magnesium-rich minerals. These minerals have a higher density compared to the minerals found in the crust, such as silica and aluminum.
Which is denser the lithosphere or asthenosphere?
The lithosphere is denser than the asthenosphere. The lithosphere is composed of the outermost layer of the Earth's crust and upper mantle, which is cooler and more rigid, while the asthenosphere is hotter and more plastic in nature, causing it to be less dense.
Why does the oceanic crust sit lower in the mantle than the continental crust?
Oceanic crust is denser than continental crust due to its composition and age, causing it to sink lower into the mantle. The oceanic crust is also thinner and has been subjected to more intense heat and pressure, which contributes to its lower position in the mantle compared to the thicker, lighter continental crust.
What are denser crustal rocks or mantle?
Mantle rocks are denser than crustal rocks. The mantle is composed of ultramafic rocks such as peridotite, which have higher densities compared to the mostly granitic rocks found in the Earth's crust. This difference in density plays a key role in the movement and dynamics of tectonic plates on the Earth's surface.
Ocean crust is denser than the continental crust because it contain more of which 3 element?
Ocean crust is typically denser than continental crust because it contains more basalt (rich in iron and magnesium), whereas continental crust is composed of less dense granite (richer in aluminum and silicon).
Is earths mantle hotter or cooler than the crust?
The mantle is hotter than the crust.
The mantle is denser than the crust because it contains more what?
The mantle is denser than the crust because it contains more iron and magnesium-rich minerals. These minerals have a higher density compared to the minerals found in the crust, such as silica and aluminum.
Is the earths core cooler than the crust and mantle?
No, the core is hotter.
Is the earth's core hotter than both the crust and the mantle.?
Yes
Is the earths core hotter than both the crust and the mantle?
Yes it is
Is the earth core hotter than both the crust and the mantle?
Yes it is
How do scientists determine mantles is denser than the crust?
The mantle is composed of basaltic rock, the crust is composed mostly of granitic rock. Basalt is denser than Granite.
Oceanic crust is denser than the continental crust because it contains more of which 3 elements?
It is the crust and mantle,and core
Why does water float on Earth's surface?
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
What is Mars' crust made of?
Basalt
Which is denser the lithosphere or asthenosphere?
The lithosphere is denser than the asthenosphere. The lithosphere is composed of the outermost layer of the Earth's crust and upper mantle, which is cooler and more rigid, while the asthenosphere is hotter and more plastic in nature, causing it to be less dense.
