Question

Name three minerals that are abundant in both oceanic and continental crust

Answer 1

Answer:

Silicon, Magnesium and Aluminum

Explanation:

    The continental crust is formed essentially of alumina silicates (hence it was formerly called sial) and has an overall composition similar to that of granite. It is 25 to 50 km thick and the primary seismic waves propagate at 5.5 km / s.

   The oceanic crust is composed essentially of basalt, formed by magnesian silicates (hence formerly called sima). It is 5 to 10 km thick and is denser than the continental crust because it contains more iron.

Answer 2

There are a plethora of these minerals in the Oceanic and Continental crust of the Earth: pyroxene, plagioclase feldspar, and olivine.
