The two main gasses are
•carbon dioxide
•oxegen
Scientists believe that the first gases that created the atmosphere came from volcanic activity and the release of gases from the Earth's interior.
Mother Earth
Geography (geology) and Chemistry
One of the main problems of using hzardious gases in an open enviroment is the wind direction, this could end up killing more people on the side in which it was released!
Inert gases are the noble gases (He, Ne, Ar, Kr, Xe, and Rn). They used to be called the inert gases until Neil Bartlett proved that you could make compounds out of some of them, so they were renamed "inert" gases.
The main gases in Earth's atmosphere are nitrogen, followed by oxygen.
Nitrogen and Oxygen
there are many gases polluting the Earth but the main 2 are oxygen and carbon dioxide.
Nitrogen (which makes up about 78% of the atmosphere) and Oxygen (about 21%)
The main gases that make up Earth's atmosphere are nitrogen (78%) and oxygen (21%). Other gases present in smaller amounts include argon, carbon dioxide, and trace amounts of gases like neon and helium.
The main gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). Other gases present in smaller amounts include argon, carbon dioxide, and traces of other gases like methane and ozone.
The 3 types of gases in Earth's atmosphere are argon, oxygen and nitrogen.
The Earth's atmosphere is composed of roughly 78% nitrogen and 20% oxygen, the remaining 2% is a mix of other gasses.
Oxygen and Nitrogen
The four main gases in primitive Earth's atmosphere were nitrogen, carbon dioxide, water vapor, and methane. These gases were likely released from volcanic activity and other processes on the early Earth.
The main gases in Earth's atmosphere are nitrogen (about 78%) and oxygen (about 21%). There are also trace amounts of other gases such as carbon dioxide, argon, and water vapor. Nitrogen and oxygen play crucial roles in supporting life on Earth.
The main gases in clean air are nitrogen (N2), oxygen (O2), and argon (Ar). These gases make up the majority of Earth's atmosphere, with smaller amounts of other gases such as carbon dioxide (CO2) and trace amounts of other gases.
