Rocks Are Not Just For Eating
Now you know that minerals from rocks are an important part of your diet. But we use rocks in other ways too. Rocks provide us with strong building materials. Rocks are used in the construction of
streets, homes, schools and other buildings in our communities. Common building stones are granite, limestone, slate and marble.
| FUN FACT: What's a rock? Some rocks are made of minerals. Salt is a rock made from a mineral called halite. Granite is a type of rock made from three
minerals: quartz, mica and feldspar. Other rocks, like coal, are made from the remains of plants and animals that lived millions of years ago.
