5. What is Rock? Rock is a substance composed of one or more minerals. Granite

6. What is Rock? It can be made out of a naturally occurring substances that do not fit perfectly into minerals. Limestone

7. What is Rock? They are placed into three groups. BasaltJasperAmethyst

8. Rock Categories Igneous Rock- These rocks are classified according to their composition and texture. Formed from cooling of molten rock. Pumice ObsidianGranite

9. Rock Categories Igneous Rock- Pumice ObsidianGranite A.Composition-refers to the minerals of rocks that are formed. B. Texture-the shape, size, arrangement, and distribution of the minerals that make up rocks

10. Rock Categories cont… Sedimentary rock-Formed from cemented sediments, minerals, or rock fragments. Have 3 categories:

11. Rock Categories cont… Clastic rocks- are made of fragments of previously existing rocks. Examples: breccia and sandstone

12. Rock Categories cont… Organic rock- come from organisms- they are formed either directly or indirectly from the material. Examples: Chalk and limestone

13. Rock Categories cont… Chemical rock-formed when a sea or lake dries up, leaving large amounts of minerals that were dissolved in the water. Examples: Rock salt and gypsum

14. Rock Categories cont… Metamorphic Rock-Formed from already existing rocks are buried deep with in the Earth, that is effected by tremendous heat, great pressure, and chemical reactions.
