What is the Earth's crust composition?
Understand the Problem
The question is asking about the composition of the Earth's crust, which involves understanding the elements and minerals that make up this layer of the Earth. The high-level approach to solve this involves identifying the primary components and their relative abundances.
Answer
The Earth's crust is 46.6% oxygen, 27.7% silicon, 8.1% aluminum, 5% iron, 3.6% calcium, 2.8% sodium, 2.6% potassium, 2.1% magnesium, and ~1.5% all other elements.
The final answer is the Earth's crust is composed of 46.6% oxygen, 27.7% silicon, 8.1% aluminum, 5% iron, 3.6% calcium, 2.8% sodium, 2.6% potassium, 2.1% magnesium, and approximately 1.5% all other elements.

More Information
The Earth's crust is predominantly composed of oxygen and silicon, forming silicate minerals, which make up more than 90% of its mass.
Tips
Misinterpreting the percentages as volume instead of mass. Always confirm if the composition is given by mass or volume.
