Greenhouse Effect A greenhouse, or a glasshouse, is a construction, roof and walls of which are made of glass. This construction is mainly used in cold weather to grow plants. What keeps the temperature warm inside the construction is the warm air. Because of the transparent panels sunlight penetrates inside and solar radiation heats up the surface under the greenhouse. Walls and roof constrain the warm air inside the construction, which allows growing plants even in sub-zero temperatures. Unfortunately, the word greenhouse left the boundaries of florists! Now it is a well-known word in biology, geology, and many other natural sciences. What our planet experiences right now and what is has been experiencing since the industrial revolution times, is called the greenhouse effect. The discussion about the greenhouse effect has long been an issue that requires a lot of concerns in society. Often it is centered around the influences that it can cause on human beings. In my opinion, the greenhouse effect is going to have massive impact on many things, including human way of life. The physics of the greenhouse effect directly resembles what happens in the original glasshouse. In other words, the surface of the Earth is heated up by sunlight, but this heat is not emitted into space, but rather it is kept within the atmosphere of the planet. This way, the greenhouse effect directly causes global warming. The processes that take place in the greenhouse effect are of course much more sophisticated and complex, however the initial structure is the same. Layers of Earth atmosphere serve as glass roof and walls, which let the sunlight inside, but do not let the heat outside. Now let us look deeper into what happens in the greenhouse effect, and which processes influence it in positive or negative ways. In general, life on Earth would not be possible without greenhouse effect.
