Rocks and Minerals (Mission: Science)

Rocks are found everywhere on Earth, and come in various sizes, shapes, colors, and textures. Some can be used to build roads, while others are used for making jewelry and glass. Rocks like coal can make electricity to heat buildings. Rocks can also hold fossils, which tell scientists about life long ago. Rocks help keep people healthy through vitamins and minerals.
