Identify rocks

About this idea

Become a geology detective by learning to identify common rocks and minerals. Discover the difference between igneous (cooled from magma like granite, basalt), sedimentary (layered like sandstone, limestone), and metamorphic (transformed by heat/pressure like marble, schist). ), crystal structure, color, and weight. 5-billion-year story—volcanic eruptions, ancient seas, mountain building.

Start with common finds, use field guides or apps like Rock Identifier, and build a labeled collection. Rock hunting gets you outdoors, teaches geology basics, and connects you to the ground beneath your feet.
