Looking at the world through via Google Earth offers striking images of the diversity of our planet and the impact that humans have had on it. Today's entry is a puzzle. We're challenging you to figure out where in the world each of the images below is taken. (You'll find answers and links at the bottom of the entry.) North is not always up in these pictures, and, apart from a bit of contrast, they are unaltered images provided by Google and its mapping partners. So I invite you to open up Google Earth (or Google Maps), have a look at the images below, and dive in. Good luck!
