Weather is the state of the atmosphere at one time and place. The atmosphere is the thin layer of gasses, like nitrogen and oxygen, surrounding the Earth. The weather rarely stays the same for very long, but changes from day to day and even changes throughout a single day or a within a few minutes!
We notice the weather every day. We wake up and think about how to dress for that day’s weather. We worry about the weather affecting our parties, ballgames, picnics, and travels. We check the weather on TV, in the newspaper and online. We comment to people we meet – sure is a nice day – or what terrible weather! Weather is a very important part of our lives.
