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.
Ocean crust is denser than the continental crust because it contain more of which 3 element?
It is the crust and mantle,and core
Why is oceanic crust always subducted underneath the continental crust?
Oceanic crust subducts under continental crust because it is denser. Continental crust's density is too low for it to be forced into the mantle.
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.
Oceanic crust is denser than the continental crust because it contains more of which three elements?
Magma,rock,iron

Why do seismic waves speed up beneath the surface of continents?
Because earths crust is denser than the mantle

What is isostatic equilibrium?
Isostatic equilibrium is the balance between Earth's crust and the layer of mantle it floats on. The denser the crust is, the more it sinks into the mantle. Equilibrium is achieved when the crust floats at a certain level in the mantle.
Which layer of the earth contains the crust and upper mantle?
The layer of the Earth that contains both the crust and upper mantle is called the Lithosphere.
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.
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.
Why does water float on Earth's surface?
Oceanic crust is denser than continental crust, it floats lower in earths mantle.
