half of earths layer
Earths under crust surrounded by Upper Mantle (35-60 km) .The mantle is composed of sillicate rocks that are rich in iron and magnesium relative to the overlying crust.
No. The crust contains a small fraction of earth's mass. Most of the mass is contained in the mantle.
earthquakes happen when these sections of earths crust move
iron and magnesium
Yes, Compression can thicken the earths crust and tension can cause thinning in the earths crust.
The way the convection cell might affect the crust above it is that it can cause the earths surface to turn into a volcano. If there is already a volcano there then it will erupt,
Plate motions produce stress in Earths crust that leads to faults, mountain building, and earthquakes.
The earths crust is a part of the outermost layer.
Silicon is a mixture of the minerals of the earths crust. so.... silicon isn't something from the earths crust. -thanks for your question.
thinner and denser
The Earths crust is approximately 650 km deep.
how wide is the earths crust
The abundance of neodymium in the earths crust is approx. 40 ppm.
Yes all metals are in the earths crust in ore form.
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
The earth's crust is not stress
