Atmospheres

An atmosphere is a layer of gases surrounding a planet or celestial body. It is essential for life on Earth, providing the air we breathe, regulating temperature, and protecting us from harmful space radiation. Earth's atmosphere consists mainly of nitrogen and oxygen, along with small amounts of other gases like carbon dioxide and water vapor. Different planets have different atmospheres; for example, Mars has a thin atmosphere, while Venus has a thick, toxic one. The study of atmospheres helps scientists understand climate, weather patterns, and the potential for life on other planets.
