Rocks Make Up Earth
The Earth is made of rocks. You can see rocks on the surface of the land, but it is not so easy to see the rocks under the water.
Big Rocks, Small Rocks
Some rocks are very big and some are very small. Stones are small rocks. Sand is made of very small pieces of rock. Many rocks are deep beneath the surface of the Earth.
Getting Rocks from a Quarry
People dig out rocks in a place called a quarry. They use tools and diggers to get the rocks.
