Shortite is a shiny, pretty rock that's made up of tiny pieces called crystals. It's special because it has two different chemical elements in it: sodium and calcium. These elements are like different colored crayons that are used to draw in a picture. Shortite is found in a special place called a mine, where people dig up rocks from under the ground. Scientists study shortite to learn more about how it was formed and what it can tell us about the Earth's history. Overall, shortite is a really cool rock that helps us understand more about our planet!
