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.
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.
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.
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.
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 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).

Yes
Yes it is
Yes it is
No, the core is hotter.
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 continental crust, it floats lower in earths mantle.
