Question

Which of the following two elements are most abundant in minerals of the Earth's crust?

1) silicon and potassium
2) silicon and magnesium
3) silicon and oxygen
4) silicon and sulfur
5) silicon and hydrogen

Answer 1

Oxygen and silicon are the two most abundant elements in minerals of the Earth's crust. They form the basis of silicate minerals, which make up approximately 92% of all minerals in the Earth's crust.

Step-by-step explanation:

Oxygen and silicon are the two most abundant elements in minerals of the Earth's crust. Oxygen constitutes about 47% of the crust by weight, while silicon makes up about 28% by weight. These two elements form the basis of silicate minerals, which make up approximately 92% of all minerals in the Earth's crust.
