Are you a busy kid? You have to attend school. You also have to do homework after school.<br />We have 24 hours every day but sometimes it seems that it isn't enough. If you've ever<br />wanted more time in the day, you're in luck. Days on Earth are getting longer each year.<br />As the moon travels around Earth, it affects Earth's rotation. It moves about 1.5 inches away<br />from Earth per year. This movement causes Earth to rotate more slowly, so days on Earth<br />are getting longer with time. Scientists believe that days are getting longer by about 0.0000018<br />each year. They studied the interaction between Earth and the moon. They found that 1.4 billion<br />years ago, a day on Earth was just 80 hours long. However, the changes are very small.<br />It takes hundreds of millions of years for them to become noticeable. You won't really<br />notice any difference in the length of days in your lifetime.
