What does green house mean?

A gaseous covering up to 400 kilometers around the Earth, which contains many types of gases, is called a greenhouse. It absorbs heat and increases its density. Generally, the surface temperature of the Earth is controlled by the solar energy falling on it and the solar energy reflected by the Earth, but when the carbon-d-oxide gas in the atmosphere quantity is more than that, then the atmospheric energy of its thick layer is not allowed to go out, due to which the temperature of the Earth's surface increases. This is called the Green House Effect or the Green Planet Effect. A greenhouse is a house, whose walls and roof are made of glass, due to which the rays of the sun come inside this house, but cannot be emitted from it, as a result of which the temperature inside the greenhouse increases.
