H2O (or water). We just learned about this in Life Science, so I remember.
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 and silicon are the two most abundant elements in the Earth's crust. They make up about 75% of the Earth's crust by weight.
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 most abundant element in Earth's crust is oxygen, making up about 46% of its mass. Silicon is the second most abundant element, comprising about 28% of the Earth's crust.
Silicon is the second most abundant element in the Earth's crust and is the principal component of sand and quartz minerals. Silicon forms the basis of silicate minerals, which make up a large portion of the Earth's crust.
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
silicon.
That would be silicon, or SiO2
Rock is the most abundant material in the crust.
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.
That element is Oxygen by 46.6%
