Quizplus · Accepted Answer

The most abundant elements in Earth's crust are silicon and oxygen, in the form of silicon dioxide (SiO2) which makes up about 60% of the crust by weight. While aluminum and iron are also abundant in the crust, they are not as abundant as silicon and oxygen. Nitrogen and oxygen are not found in significant abundance in the crust.
