How can you tell a rock is igneous?
Igneous rock is created by volcanic activity, forming from magma and lava as they cool and harden. It is most often black, gray, or white, and often has a baked appearance. Igneous rock may form crystalline structures as it cools, giving it a granular appearance; if no crystals form, the result will be natural glass.
What are igneous rocks used for in everyday life?
Igneous rocks have a wide variety of uses. One important use is as stone for buildings and statues.
