The most abundant element in the Earth’s crust is oxygen. Oxygen comprises approximately 46.6% of the Earth’s crust by mass. It is a key component of many minerals such as silicon dioxide (silica), aluminum oxide, and iron oxide, which are present in various forms, including rocks, sand, and clay. Oxygen also plays a crucial role in the formation of compounds and minerals, making it an essential element for sustaining life on Earth. Furthermore, oxygen is a fundamental element in the composition of the atmosphere, making up about 21% of air by volume. Its abundance in the Earth’s crust and atmosphere highlights its significance in the geological and biological processes that shape our planet.
