3.Learn About Your World with Google Earth

Google Earth plays second-fiddle to Maps quite a bit, as they have a lot of overlapping features. When it comes to practical day-to-day tasks like finding food or getting directions, Maps has you covered. For everything else, though, Earth is truly the superior product. One of the more useful functions is the ability to measure distances with a higher degree of accuracy than Maps. If taking account of tedious trivia isn't your schtick, Earth offers a variety of other features that can reveal the nature of the world around you. In many areas, Earth has over two decades of map data. By using the time slider, you can view what a particular area looked like in the past. Alternatively, if the terrestrial world doesn't interest you, Google Sky (which is part of the Earth software), allows you to view all of the images of the universe Google has collected on its servers.
