This memory game has a challenging twist. The pairs of images are not identical. Instead, they are before and after images of a location that has experienced a type of land change.
Find the matching image pairs of the same location—then try again and see if you can improve your time! The options below give you a variety of difficulty levels. Click the number of pairs you’d like to match up.
Find a growing river delta and an expanding city—but a shrinking glacier—in the images for this memory game.
What can cause changes to coastlines? Landsat shows you in some of the images in this set.
The difficulty level ramps up in this game! One of the largest areas of deforestation appears in one of these image pairs.
The game was inspired by Pia van Benthem, CaliforniaView, using imagery from the USGS Earthshots website, which has imagery from more than 100 locations.
