There, the gas particles are pressed together by the weight of the air above them. What are these seasonal winds known as? We often call the atmosphere “air.” All planets have an atmosphere, but Earth is the only planet with the correct combination of gases to support life. Chemistry. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. Most of Earthâs weather, including the wind and most clouds, exists in the troposphere. The Earth’s atmosphere extends about 6,000 miles above its surface. The atmosphere protects life on Earth by absorbing ultraviolet solar radiation and reducing temperature extremes between day and night. The atmosphere is the layer of gas that surrounds Earth.

Atmospheric science is the study of the Earth's atmosphere and its various inner-working physical processes. There is no definite boundary between the atmosphere and outer space. Outgassing is the release of gas that was trapped in some other material. Earth's atmosphere. The stratosphere includes the ozone layer. Earth's atmosphere is the only one in the solar system capable of supporting life. It is often called air. Most of our atmosphere is located close to the earth's surface where it is most dense. Its atmosphere is dominated by carbon dioxide, and features swirling clouds of sulfuric acid. As height increases, the air molecules become separated by more space, and the weight decreases. … The atmosphere is also responsible for the aurora borealis. atmosphere: The envelope of gases surrounding Earth or another planet. It extends up to about 50 miles (80 kilometers) above Earthâs surface. Please note: Text within images is not translated, some features may not work properly after translation, and the translation may not accurately convey the intended meaning. The third layer is the mesosphere. As the weight of the air decreases, so does the air pressure. Meteorology includes atmospheric chemistry and atmospheric physics with a major focus on weather forecasting. An atmosphere is more likely to be retained if the gravity it is subject to is high and the temperature of the atmosphere is low. Nature has equipped Earth with several giant "sponges," or carbon sinks, that can help humans battle climate change. Atmospheric science includes the study of composition, circulation, and the chemical and physical processes of the atmosphere. A body is more likely to retain an atmosphere over time if gravity is high and the temperature of the atmosphere is low. Other planets, and some of their larger moons, also have atmospheres.
