Have you ever picked up a shiny stone and wondered what it’s made of? This quiz helps you explore rocks and minerals — the natural treasures that make up Earth’s surface.
You’ll learn about igneous, sedimentary, and metamorphic rocks, and how heat, pressure, and time shape them.
Each question builds your scientific understanding and teaches you how minerals give rocks their colors, patterns, and strength.
You’ll also discover how we use these materials in buildings, jewelry, and everyday tools.
