What's the difference between atmosphere and weather?
The air covers the earth's surface layer by layer, transparent, colorless and tasteless. It is mainly composed of nitrogen and oxygen, which has an important impact on human survival and production.
The atmosphere is the air around the earth. Phenomenologically speaking, weather is mainly the result of moisture changes in the atmosphere. Under the combined action of solar radiation, underlying surface forcing and atmospheric circulation, the long-term comprehensive situation of weather is called climate.
2, the composition is different
Air refers to the mixture of gases in the earth's atmosphere, so air belongs to the mixture, mainly composed of nitrogen, oxygen, rare gases (helium, neon, argon, krypton, xenon, radon, helium), carbon dioxide and other substances (such as water vapor and impurities).
The atmosphere refers to a thick layer of atmospheric molecules gathered around the earth, called the atmosphere. Humans, like fish living in water, live in the bottom of the earth's atmosphere and can't live without it for a moment.
3. Different characteristics
Oxygen in the air is necessary for all aerobic organisms. All animals need to breathe oxygen, so do green plants. In addition, green plants use carbon dioxide in the air for photosynthesis, and air is almost the only source of carbon dioxide needed by all plants.
The movement of the atmosphere is caused by the exchange of heat energy in the atmosphere, which mainly comes from the sun. The exchange of heat energy makes the temperature of the atmosphere rise and fall. The movement of air and the change of air pressure system make the energy and materials between land, north and south, ground and sky exchange continuously, resulting in complex meteorological and climate changes.
