The two most abundant gases in any layer of the atmosphere are nitrogen and oxygen. In the stratosphere, ozone composition increases from 0.04 parts per million in other layers to 5-12 ppm. However, this does NOT make ozone more abundant than nitrogen and oxygen.
The two most abundant gases in clean dry air are nitrogen, making up about 78%, and oxygen, making up about 21%.
The most common compounds found in the atmosphere are nitrogen and oxygen. Of the two, nitrogen is more abundant and keeps oxygen inert.
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 two most abundant element's in the earth's crust are oxygen and silicon. Refer to the related link to see a list of the most abundant elements in the earth's crust.
The two most abundant elements in the Earth's crust are: Oxygen (46.1%/461,000ppm), and Silicon (28.2%/282,000ppm).
The two most abundant gases in the Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%).
