planetary atmospheres
Planetary atmospheres are layers of gases surrounding planets, held in place by gravity. They can vary greatly in composition, thickness, and temperature. Earth’s atmosphere, for instance, is rich in oxygen and nitrogen, supporting life, while Venus has a thick atmosphere full of carbon dioxide, making it extremely hot. The atmosphere plays crucial roles, including protecting planets from space radiation, regulating temperatures, and influencing weather patterns. Understanding atmospheres helps us learn about a planet's climate, potential for life, and even its history, providing insights into our own planet and others in the universe.

Planetary atmospheres refer to the layers of gases surrounding a planet. They can vary widely in composition, density, and temperature. Earth's atmosphere, for instance, is rich in oxygen and nitrogen, supporting life. Other planets, like Venus, have thick atmospheres that trap heat, while Mars has a thin atmosphere mostly made of carbon dioxide. These atmospheres affect weather patterns, climate, and even the potential for life. Understanding them helps scientists learn about a planet's history and its ability to support life.
