¿Qué es el aire?

Air is an essential, invisible mixture of gases surrounding Earth, primarily composed of nitrogen and oxygen. It supports life by providing oxygen for animals and carbon dioxide for plants. Air also plays a role in sound and odor transmission and is used in technology like wind turbines. Without air, life on Earth would not exist.
