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

Biology
2 answers:
MatroZZZ [7]3 years ago
5 0

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.

Can someone help me make a hypotheses?
egoroff_w [7]
Since a hypothesis is a statement rather than a question, you could simply restate the line given to you in line 1.  (That is of course your hypothesis is on the subject of people and social media.)

If I were to make a hypothesis off of that subject I would use something along the lines of:

"People who use social media more than others are more likely to struggle with social skills face to face."

Hope this helps! :)
