The crust is the thinest and coolest of all Earth's layers. It is broken into plates known as tectonic plates and is constantly recycling and renewing itself.
It is made of hard rock.
the temperture varies
It is the most common rock in the crust of the Earth.
the temperture varies
Yes, and in fact is very abundant.
The lithosphere is composed of the oceanic and continental crust, along with the brittle uppermost mantle. The continental crust is mainly granitic, and the oceanic crust is primarily basalt.
that the moon has a thinner crust on the side facing earth
No, the continental crust is generally thicker and less dense than the oceanic crust. Continental crust can be up to 70 km thick in some areas, while oceanic crust averages about 7 km in thickness. Density-wise, oceanic crust is denser because it is made mostly of basalt, whereas continental crust is primarily composed of less dense granite and sedimentary rocks.
Natural francium is very scarce - approx. 30 g in the Earth crust.
Do you mean empanadas? If so, they are stuffed pies. The crust is very similar to pie crust (in fact you can use premade pie crust to make them). The filling is anything you like. Sometimes they are sweet with raisins and nuts and sometime savory with ground meat.
Mars has virtually no magnetic field because the crust below the surface is so thin.
This is called a destructive plate boundary. It occurs due to the fact that the oceanic crust is far denser than the continental crust. As a result it subducts into the mantle and is incenerated. Hope it helped:)
