Rocks that are lying on the ground might look gray and boring. If you zoom in on them with a microscope, though, you will see lots of colourful little pieces. Look inside to find out how these tiny pieces - called minerals - make up all the rocks on Earth. You'll also get a look at new cars, ancient gold coins, and sparkling rubies, emeralds, and diamonds - since all of these are make up of minerals from rocks, too.
