Some common examples of greenhouse gases include:
* Carbon dioxide (CO2)
* Methane (CH4)
* Nitrous oxide (N2O)
* Water vapor (H2O)
* Ozone (O3)
These gases act like a blanket, trapping some of the sun's heat and preventing it from escaping back into space. This process is known as the greenhouse effect, and it's what keeps Earth warm enough to support life.
However, human activities are increasing the concentration of greenhouse gases in the atmosphere, leading to global warming and climate change.
