Answer Details
The most important element on Earth's crust is oxygen. Oxygen makes up about 46.6% of the Earth's crust by weight and is an essential component of many minerals and compounds that make up the Earth's crust. It also plays a critical role in supporting life on Earth, as it is necessary for respiration in most living organisms. Additionally, oxygen is involved in many geological processes, such as the weathering of rocks and the formation of soils. The abundance of oxygen in the Earth's crust and its importance to both geology and biology make it the most important element on the Earth's crust.
