The atmosphere is the layer of gases surrounding a planet, held in place by gravity. It plays a crucial role in supporting life, regulating temperature, and facilitating weather patterns. Earth's atmosphere is composed mainly of nitrogen, oxygen, and trace gases, and it protects the planet from harmful solar radiation. Additionally, it enables processes such as photosynthesis and the water cycle, which are vital for sustaining ecosystems.
