Google Earth is a free application for Macs and PCs. It’s a lot like Google Maps but in 3D. Using a vast repository of satellite and aerial photography and topographical data, the software allows you to explore the world (and the oceans and sky) in a highly interactive application.
There is a wealth of knowledge in Google Earth to explore for educational purposes. Advancements over the last few years have brought historical satellite imagery to Google Earth for public use, in some areas ranging back as far as 75 years. That’s not to mention the scores of “layers” developed by non-profit and educational organizations on topics ranging from genocide and human rights to climate change and global warming. If you’ve used Google Maps to search for local goods and services, then you’ll understand how layers work. Just like you can view the location of the local theater down the street in Google Maps, you can also see icons and placemarks in Google Earth. Google Earth is like Google Maps on Steroids.
