ROCKS are inorganic natural substances. They are normally composed of more than one mineral. There are 3 main types of rocks depending on how they are formed.
1. IGNEOUS ROCKS (ígneas): these rocks form when molten lava from volcanoes cools and hardens. For example: granite and basalt.
2. SEDIMENTARY ROCKS (sedimentarias): layers of other rocks fragments, animal or plant fossils. They compact over millions of years to form rock. For example: clay and limestone.
3. METAMORPHIC ROCKS (metamórficas): igneous or sedimentary rocks that are transformed into a new rock. If rocks are buried deep in the earth at high temperatures and pressures, they form metamorphic rocks. For example: marble and slate.
