In the earth crust: silicon, aluminium, oxygen.
The two most common elements found in the Earth's continental crust are oxygen and silicon. Oxygen is the most abundant element, making up about 46.6% of the Earth's crust by weight, while silicon is the second most abundant, making up about 27.7%.
The two most common elements in Earth's crust are oxygen and silicon. Oxygen makes up about 46% of the Earth's crust by weight, while silicon makes up about 28%.

Hydrogen is the most common element in the universe. Helium, Oxygen, silicon, and aluminum are the next most common elements in the universe and on earth.
The two most common elements in the Earth's crust are oxygen and silicon. Oxygen makes up about 46.6% of the Earth's crust by weight, while silicon makes up about 27.7%.
The three most common elements in Earth's continental crust are oxygen, silicon, and aluminum. In the oceanic crust, the predominant elements are oxygen, silicon, and magnesium. While oxygen and silicon are abundant in both types of crust, aluminum is more prevalent in the continental crust, whereas magnesium is more common in the oceanic crust.
