The greenhouse effect, also known as the "greenhouse effect", is a common name for the atmospheric heat preservation effect. The atmosphere can make the short-wave radiation of the sun reach the ground, but a large number of long-wave radiation rays emitted by the ground are absorbed by the atmosphere after being heated, which makes the temperature of the ground and the lower atmosphere rise. Because its function is similar to the greenhouse for cultivating crops, it is named the greenhouse effect.

Reason: The greenhouse effect is mainly caused by the excessive burning of coal, oil and natural gas in modern industrial society, and a large amount of carbon dioxide gas contained in automobile exhaust gas is released into the atmosphere.

Impact: Greenhouse gases effectively absorb infrared radiation emitted by the same gases and clouds on the earth's surface and the atmosphere itself. Atmospheric radiation is emitted in all directions, including to the surface of the earth below.

Greenhouse gases capture heat in the ground troposphere system, which is called "natural greenhouse effect". Atmospheric radiation is closely related to the temperature level of its gas emission. In the troposphere, the temperature generally decreases with the increase of altitude.

Characteristics of greenhouse effect:

Glass greenhouses and vegetable greenhouses that can be seen in life are typical greenhouses. Make a greenhouse with glass or transparent plastic film, let the sun shine directly into the greenhouse and heat the indoor air.

The glass or transparent plastic film can prevent the indoor hot air from emitting outwards, so as to keep the indoor temperature higher than the outdoor temperature and provide conditions conducive to the rapid growth of plants. The reason why this effect is called greenhouse effect is also related to this principle.
