What makes igneous rocks different from the other type of rocks?
igneous rocks are formed when a volvano erupts, and then the lava cools. Sedimentary rocks are formed when parts of mountains, earth, and bigger rocks are broken down into sediments because of weathering and erosion, then compacted. Metamorphic rocks are formed when rocks become extremely hot underneath the earth’s surface until they are actually flexible, then they twist and morph, and then cool.
