Question

what does the troposphere contain most of in the atmosphere?

Answer 1

The troposphere, which is the lowest layer of Earth's atmosphere, contains most of the atmosphere's mass, including approximately 75% of its gases. It is primarily composed of nitrogen (about 78%) and oxygen (about 21%), along with trace amounts of other gases such as argon, carbon dioxide, and water vapor. The troposphere is also where most of the weather phenomena occur, as it contains the majority of the atmosphere's water vapor and clouds.
