Where Do Rocks Come from?


Rocks are divided according to how they are formed. The igneous rocks are formed when molten rock cools down from volcanic activity. The sedimentary rocks are formed through wethering and erosion of other rocks. Finally, the metamorphic rocks are formed when either sedimentary or igneous rocks are heated underground at really high temperatures.
