===About the Greenhouse Effect===
: The '''greenhouse effect''' is caused by [[gas]]es in the [[atmosphere]] being more [[transparent]] to [[Visible Light|visible light]] from [[The Sun]] than [[Infrared Light]] [[emit]]ted from the surface of the [[planet]]. The [[Visible Light]] from [[The Sun]] strikes the surface of the [[planet]] causing the surface to increase in [[temperature]]. The surface cools by [[emit]]ting [[Infrared Light]]. If the [[atmosphere]] traps the [[Infrared Light]] the [[atmosphere]] will increase in [[temperature]].
: Some [[gas]]es have a greater '''greenhouse effect''' than others. [[Carbon Dioxide]] and [[Methane]] has a strong '''greenhouse effect''' so they are called [[Greenhouse Gas|greenhouse gases]].
: The '''greenhouse effect''' is essential to keep the [[Earth]] warm enough for [[liquid]] [[water]]. If there were no [[Greenhouse Gas|greenhouse gases]] the [[Earth]] would cool and the [[ocean]] would [[freezing|freeze]].
: If the [[percentage]] of [[Greenhouse Gas|greenhouse gases]] were to get too high the [[Mean Average|average]] [[temperature]] of the [[Earth]] would increase due to the '''greenhouse effect'''.
