The atmosphere protects the Earth and all the life on it by absorbing harmful ultraviolet radiation from the Sun and providing us with the air we need to breathe. It also helps to regulate the temperature on the Earth’s surface, and it allows for the movement of weather systems. The atmosphere is an important part of the Earth’s ecosystem, and it plays a crucial role in supporting life on the planet.
