What Are The Two Most Abundant Elements In Earth S Crust

Oxygen is the most abundant element in the earth s crust at 461 000 parts per million.

By themselves they make up over 90 of the weight of the earth s crust. The crust is chemically similar to andesite. The elements in the outermost surface of the earth the crust are found mostly in trace amounts. Oxygen and silicon are the two most abundant elements by mass in the earth s crust oceans and atmosphere.

Oxygen 46 1 461 000ppm and silicon 28 2 282 000ppm. Oxygen 46 1 461 000ppm and silicon 28 2 282 000ppm. What are the most common elements in th. This means it makes up roughly 46 of the earth s crust.

Most common elements on earth. Most rocks are composed mainly of this class of minerals. Estimates of elemental abundance are difficult because a the composition of the upper and lower crust are quite different and b the composition of the continental crust can vary. Silicates are the most widespread of the minerals.
