Which elements comprises the highest percentage of the earth's crust: Oxygen, Iron, Calcium
Answer: Oxygen. Even though there are 92 elements that are naturally found, only eight of them are common in the rocks that make up the Earth's outer layer, the crust. The 8 most common elements (by mass): 46.6% Oxygen (O), 27.7% Silicon (Si), 8.1% Aluminum (Al), 5.0% Iron (Fe), 3.6% Calcium (Ca), 2.8% Sodium (Na), 2.6% Potassium (K) and 2.1% Magnesium (Mg)
