Oxygen is the most abundant element in Earth's crust, making up about 47% of its mass. Silicon is the second most abundant element, comprising approximately 28% of the crust's mass.
Aluminum is the Earths most abundant metal and its located in the Earths outer crust.One of the properties of crust is that it consists of a variety of sedimentary,metamorphic and igneous 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.
Magnesium makes up about 2% of the Earth's crust by weight, making it the eighth most abundant element.
Igneous and metamorphic rock make up 95% of the rocks in Earth's crust. Only a thin layer is made up of sedimentary rock.
Silicates make up close to 95 percent of the rocks in the Earth's crust
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 element found in both biotite mica and muscovite mica that makes up the greatest percentage by volume of Earth's crust is oxygen. Oxygen is a very abundant element in the Earth's crust, forming the majority of the minerals and rocks that make up the Earth's surface.
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.
Nitrogen makes up 78% of Earth's atmosphere.
This element is calcium. It is the fifth most abundant element in the Earth's crust and makes up more than 3 percent of the crust. It reacts with water and belongs to the 2nd group of the periodic table.
The principle element found at the Earth's core is iron.
Oxygen is the most abundant element in Earth's crust, making up about 47% of its mass. Silicon is the second most abundant element, comprising approximately 28% of the crust's mass.
Nitrogen, which is an element. It has atomic number 7 on the Periodic Table of Elements.
Silicates make up about 90% of Earth's crust. These minerals are composed of silicon and oxygen, along with other elements like aluminum, iron, calcium, and magnesium. Silicate minerals are the building blocks of most rocks on Earth's surface.
