Rocks and stones are hard solids of natural origin and made of minerals. Some common rocks can be scratched with your fingernails such as shale, soapstone, gypsum rock, and peat. Others may be soft in the ground, but they harden once they spend time in the air. There are three main types of rocks:

Igneous rocks are formed when melted rock (magma) cools and solidifies. Some igneous rocks are formed when the magma erupts from a volcano. Obsidian, basalt, and granite are all examples of igneous rocks.

Sedimentary rocks are created when layers of sediment (minerals, other rocks, or organic material) are compressed over time. Chalk, limestone, and flint are all examples of sedimentary rocks.

Metamorphic rocks are formed when igneous and sedimentary rocks are changed by intense heat or pressure. Marble (from limestone, a sedimentary rock) and granulite (from basalt, an igneous rock) are examples of metamorphic rocks.

Ideas for Learning About Rocks

Rocks are fascinating and easy to find. Try these activity ideas for learning more about them:

Start a collection. Pick up rocks when you're on nature walks (if doing so is allowed) or out running errands. Look for rocks from different areas when you travel out of state. You may even ask out-of-state friends and relatives to send you interesting rocks that they find. Identify the rocks you find. An empty egg carton makes a great storage container for small rocks. You can write the name of each rock in the slot made to hold the eggs or make a key inside the carton lid.Learn about the rock cycle.Visit a natural history museum or planetarium. Most will have a rock collection on display.Experiment with your rock collection. Is your rock magnetic? Does it float? How much does it weigh?Make a pet rock.
