Question

What do you mean by greenhouse effect?

Answer 1

Hint: In the atmosphere of a planet, radiatively active gases (i.e. greenhouse gases) emit energy in all directions. A portion of this radiation is reflected back to the surface, warming it. The amount of greenhouse gases in the atmosphere determines the intensity of downward radiation, or the degree of the greenhouse effect. The temperature rises until the downward flow of energy is balanced by the intensity of upward radiation from the surface, which cools it.

Complete answer: The absorption of infrared radiations of long wavelengths produced from the planet's surface by freon house gases such as carbon dioxide, water vapour, methane, nitrous oxide, ozone, chlorofluorocarbons (CFCs), and others causes the earth's surface and lower atmosphere to warm. The greenhouse effect is the process through which solar energy is absorbed by greenhouse gases instead of being reflected back into space. This keeps the earth's surface warm and prevents it from freezing. The gases that absorb infrared radiation and cause the greenhouse effect are known as greenhouse gases. Carbon dioxide and chlorofluorocarbons, for example. A greenhouse is a glass structure that is used to cultivate plants. The greenhouse's plants and air are warmed by the sun's rays. The heat trapped within cannot leave, warming the greenhouse, which is necessary for plant development. The same is true of the earth's atmosphere. The sun warms the earth's atmosphere during the day. Heat is reflected back into the atmosphere when the earth cools at night. The heat is absorbed by the greenhouse gases in the earth's atmosphere throughout this process. This is what keeps the earth's surface warm, and what allows living things to survive on the planet.

Note:
Most diatomic gases with two distinct atoms (such as carbon monoxide, CO) and all gases with three or more atoms may absorb and emit infrared radiation, making them greenhouse gases. Intermolecular collisions cause the energy absorbed and emitted by the greenhouse gases to be shared with the other, non-IR-active gases, despite the fact that more than 99 percent of the dry atmosphere is IR transparent (because the main constituents - \[{N_2},{\text{ }}{O_2}\], and $Ar$ -cannot directly absorb or emit infrared radiation).
