Answer 2

A greenhouse is a structure, usually made of glass, in which temperature and humidity can be controlled for the cultivation or protection of plants. A greenhouse is designed to trap heat from the sun’s rays inside and acts to keep the plants inside warm, even when it is cold outside. Although the Earth does not have a layer of clear material over it, certain molecules in our atmosphere absorb the Earth’s heat, basically trapping some of that energy. This is called the greenhouse effect, and the molecules that trap the heat are called greenhouse gases.
