What are green house gases or atmospheric gases?

Answer 1

Atmospheric gases trap heat so that Earth is not a frozen wasteland. Greenhouse gases is the term used to refer to heat-trapping gases such as carbon dioxide and methane because these gaseous components of the atmosphere make Earth function like a greenhouse-heat from the Sun that is reflected off the Earth is reflected back up to the atmosphere and the greenhouse gases trap some of this heat.

Understand that greenhouse gases are necessary to retain some of the Sun's heat, but they are bad in excess; to much carbon dioxide( a greenhouse gas) contributes to global warming-too much heat from the Sun is trapped by the atmosphere so that temperatures on the surface rise.

Answer 2

Greenhouse gases are gases in Earth's atmosphere that trap heat, leading to the greenhouse effect and global warming. Examples include carbon dioxide (CO2), methane (CH4), and water vapor. These gases contribute to climate change by absorbing and emitting radiation within the thermal infrared range.
