The most common element in the Earth's crust is oxygen. Oxygen makes up about 46.6% of the Earth's crust by weight. It is the third most abundant element in the universe, after hydrogen and helium. Most of the oxygen in the Earth's crust is in the form of oxides, such as silicon dioxide (SiO2), which is the main component of sand and quartz, and aluminum oxide (Al2O3), which is the main component of many types of rock, including clay and bauxite. Oxygen also makes up about 21% of the Earth's atmosphere.
The second most common element in the Earth's crust is silicon, which makes up about 27.7% of the Earth's crust by weight. It is the main component of minerals such as quartz and feldspar, and it is also a major component of many types of rock, including granite and sandstone.
The third most common element in the Earth's crust is aluminum, which makes up about 8.1% of the Earth's crust by weight. It is the main component of minerals such as bauxite and corundum, and it is also a major component of many types of rock, including clay and granite.
The fourth most common element in the Earth's crust is iron, which makes up about 5% of the Earth's crust by weight. It is the main component of minerals such as hematite and magnetite, and it is also a major component of many types of rock, including basalt and granite.
In conclusion, the most common element in the Earth's crust is oxygen, which makes up about 46.6% of the Earth's crust by weight. The second most common element is silicon, making up about 27.7% of the Earth's crust. The third most common element is aluminum, making up about 8.1% of the Earth's crust and the fourth most common element is iron making up about 5% of the Earth's crust by weight. These four elements are the main building blocks of the Earth's crust and are present in many minerals and rocks that make up the Earth's surface.
