Explanation
Air is the invisible gas we breathe that surrounds the Earth. It’s made of oxygen and other gases and is essential for life. We also use the word “air” to talk about open space or the sky, like “fresh air” or “through the air.” It can even be used in expressions like “put something in the air” (to talk about atmosphere or feeling).
