Reflection on Google Earth

I've always thought Google Earth was cool and fun to play with, but I hadn't thought of it as an educational tool. I think its great for learning about Geography, History, Literature, and many other topics. You can do almost anything with it (except see the breathtaking views of mountains and water from the top of a hill). It cannot replace the real thing but it can get pretty close. The site that I found had many different tours in many different topics and places. I hope I can use them and any others that I find.
