HELP PLEASE Can you say in your own words, what you think is the difference between a greenhouse gas and a non-greenhouse gas? I've been trying for a while to compare them and I'm just confused and don't know what to do

Unlike a greenhouse, the Earth does not have a layer of glass over it. Instead, molecules in our atmosphere called greenhouse gasses absorb the heat. Greenhouse gasses include water vapor, methane, ozone, nitrous oxide, and carbon dioxide.
