half of earths layer
What is the earths under crust surrounded by?
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.
How do floods affect the earths crust?
it gets soggy
Is it true that earths crust contains most of earths mass?

How did the napier earthquake occur?

How does stress change earths crust?
It causes it to deform - this deformation is called "strain".
Where do most faults occurs?
Most Faults Occur Where The Earths Crust Is Extended
How do motions affect Earth's crust?
Plate motions produce stress in Earths crust that leads to faults, mountain building, and earthquakes.
