Air is one of the four basic elements of life. It is the invisible gas that surrounds us and makes up the atmosphere. We need air to breathe, and it also protects us from harmful UV rays from the sun.
While we may not be able to see it, air is all around us and plays a vital role in our lives. Without air, we would not be able to survive for more than a few minutes. This simple element is essential for life as we know it, and yet we often take it for granted.
The next time you step outside, take a deep breath and appreciate the gift of air that keeps you alive and healthy!
The word air has thought to have originated from the Latin word for wind, aer. This word eventually made its way into English in the 14th century. It wasn’t until the 16th century that air began to be used as a term for the atmosphere.
Interestingly, the word atmosphere comes from two Greek words: atmos, meaning vapor or steam, and sphaira, meaning ball or sphere. So when we talk about the atmosphere of Earth, we are really talking about a giant sphere of air!
The study of air is called aerology and there is a lot still unknown about this vital element that sustains all life on Earth. But what we do know is that without it, none of us would be here today!
