The two main components in the atmosphere that play a major role in weather and climate change are.

The main components in the atmosphere that play a major role in weather and climate are carbon dioxide, ozone and water vapor.

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.

The atmosphere is composed of a mixture of gas, liquid and solid impurities suspended in it. As a gas mixture, its composition is relatively stable. 78% of the dry air is nitrogen, 2 1% is oxygen, and the rest is some other gases. However, gases with relatively small specific gravity such as carbon dioxide, ozone and rare gases are also important. Secondly, the existence of water in the atmosphere is as important as oxygen. In the temperate zone near the surface, the average proportion of water vapor is 65438 0%.

The main cause of climate change is air pollution.

The influence of air pollution on the physical state of the atmosphere is mainly caused by abnormal climate changes. Sometimes this change is obvious, sometimes it happens in the form of gradual change, which is difficult for ordinary people to detect, but if left unchecked, the consequences may be very serious.

Any substance that can worsen air quality is an air pollutant. There are natural factors (such as forest fires and volcanic eruptions). ) and human factors (such as industrial waste gas, domestic coal burning, automobile exhaust, etc. ), and the latter is the main factor, especially caused by industrial production and transportation. The main process consists of three links: pollution source discharge, atmospheric transmission and human suffering.
