Green houses are the artificial enclosures that let the light in and trap the heat to create an environment suitable for plant growth. http://www.lmgtfy.com/?q=green-house certain gases collect in the atmosphere and create a similar effect by trapping solar heat within the atmosphere and the surface temperature on earth increases, just like in green-houses.
