Detailed explanation-1: -Oxygen, silicon, aluminum, and iron account for 88.1% of the mass of the Earth’s crust, while another 90 elements make up the remaining 11.9%.

Detailed explanation-2: -1. Oxygen, aluminum, calcium, iron, and silicon are the most abundant elements in Earth’s lithosphere.

Detailed explanation-3: -It is the topmost layer of the earth, but the thing it is that this crust contains so many elements and out of those elements, silicon element-silicon is element which is, we can say, present in the solid state.

Detailed explanation-4: -Answer and Explanation: The element that is most abundant in the Earth’s lithosphere is oxygen. Oxygen makes up 460, 000 parts per million (ppm) with silicon making up 277, 200 ppm as the second most abundant, with aluminum a far third at 81, 300 ppm.

Detailed explanation-5: -Each element is assigned a symbol-H for hydrogen. You should learn the symbols for the eight most abundant elements in the Earth’s crust (Oxygen (O), Silicon (Si), Aluminum (Al), Calcium (Ca), Iron (Fe), Magnesium (Mg), Sodium (Na), and Potassium (K) .
