A Kid’s Guide to Geology

Geology is the study of the Earth — its rocks, minerals, volcanoes, fossils, and the forces that shape the ground beneath our feet. This curated guide gathers the best, most trustworthy geology resources for young rock hounds, students, and teachers.

Dig Into the Earth

From the rocks in your backyard to towering mountains and rumbling volcanoes, geologists study how our planet formed and how it keeps changing. The trusted resources below — from the U.S. Geological Survey, the Smithsonian, and more — will help kids explore rocks and minerals, play and learn, and dig deeper into earth science.

Frequently Asked Questions

Geology basics for curious kids and their grown-ups.

Geology is the science of the Earth — what it’s made of, how it formed, and how it changes over time through forces like volcanoes, earthquakes, and erosion. Scientists who study it are called geologists.

Igneous rock forms when melted rock (magma or lava) cools and hardens. Sedimentary rock forms from layers of sand, mud, and shells pressed together over time. Metamorphic rock forms when heat and pressure change an existing rock into a new one.

Start by collecting interesting rocks from your yard, a park, or a beach (with permission — collecting isn’t allowed in national parks). Wash them, label where you found each one, and use a guide like Mindat or Geology.com to identify them. An egg carton makes a great starter display.
