Carbon
One is silicon, but I don't know the other:(oxygen
In the Earth's crust, the five most abundant elements by weight are oxygen, silicon, aluminum, iron, and calcium. In water, the most abundant elements by weight are hydrogen and oxygen. In the atmosphere, the most abundant elements by volume are nitrogen, oxygen, argon, and carbon dioxide.
Oxygen, silicon, aluminum, iron, calcium, sodium, potassium, and magnesium are the most common elements found in Earth's continental crust.
The most common element in the earth's crust is oxygen.

The most common elements in the universe are, Carbon, Oxygen, Nitrogen, Iron and Hydrogen,
Carbon
Oxygen and silicon are the two most abundant elements found in the most common minerals. The most common minerals found on Earth are silicates.
The five most common elements found on Earth are oxygen, silicon, aluminum, iron, and calcium. These elements make up a significant portion of the Earth's crust and are essential building blocks for the planet's geology and biology.
