Question 1

Compare and contrast the mantle and crust.

Accepted Answer

The crust is the outermost layer of the solid Earth and the mantle lies below the crust and above the outer core.The mantle is nearly 3000 km thick and consists mostly of soft plastic to solid material composed of Fe and Mg-rich silicate minerals with a density of 4.5 g/cm3.The crust is composed of cooler solid rock material,is only several km thick (max.4 km)and is much less dense - 2.8 g/cm3.This density contrast defines their boundaries as marked by the Mohorovicic discontinuity,or Moho.
