Silicon & Oxygen (rocks).
The fifth most abundant element in the Earth's crust is potassium. It makes up about 2.6% of the Earth's crust by weight.
Oxygen is the most abundant element in the Earth's crust, making up about 46.6% of its mass.
Feldspar is the most abundant group of rock-forming minerals in the Earth's crust. It makes up about 60% of the Earth's crust and comes in different varieties such as orthoclase, plagioclase, and microcline. Feldspar is commonly found in igneous and metamorphic rocks.
The element that is a member of the boron family and the most abundant in Earth's crust is aluminum. It makes up about 8% of the Earth's crust and is commonly used in various industries due to its lightweight and corrosion-resistant properties.
The Earth's crust is primarily made up of oxygen (46.6%) and silicon (27.7%), with silicon being the second most abundant element in the crust.
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
The fifth most abundant element in the Earth's crust is potassium. It makes up about 2.6% of the Earth's crust by weight.

Oxygen is the most abundant element in the Earth's crust, making up about 46.6% of its mass.
The Earth's crust contains eight elements. The most common element among the eight is Oxygen (47 percent) and second is Silicon (28 percent).
Feldspar is the most abundant group of rock-forming minerals in the Earth's crust. It makes up about 60% of the Earth's crust and comes in different varieties such as orthoclase, plagioclase, and microcline. Feldspar is commonly found in igneous and metamorphic rocks.
In terms of weight, iron makes up approximately 5% of the earths crust, the fourth most abundant element in the crust. However, remember Earth's Core is nearly all Iron.
