and Planetary Atmospheres

Planetary atmospheres are layers of gases that surround planets, created by various processes like volcanic activity or solar wind capture. They vary widely in composition, density, and temperature, affecting a planet’s climate, weather, and potential habitability. For example, Earth's atmosphere contains nitrogen and oxygen, supporting life, while Venus has a thick, carbon dioxide-rich atmosphere causing extreme heat. Atmospheres influence a planet's surface conditions, protect from harmful radiation, and can create phenomena like clouds or storms. Studying atmospheres helps scientists understand planetary environments, their evolution, and possibilities for life beyond Earth.
