Hydrogen I believe
That element is Oxygen by 46.6%
The most common element in the Earth's Crust is: Iron 33% Atmosphere: Oxygen 85% Ocean: Oxygen 65% Good Luck, Textbo7
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.
The second most abundant element in the Earth's crust is silicon, comprising 27.8% of the crust by mass.
Aluminum :D
Silicon
Oxygen is the most abundant element in the Earth's crust, atmosphere, and oceans. It makes up about 46% of the Earth's crust by weight, about 21% of the atmosphere, and is a key component of water in the oceans.
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.
The most abundant element in Earth's crust is oxygen, making up about 46.6% of the crust by weight.
That would be silicon, or SiO2
silicon
Aluminum 7.5 to 8.1%
