Across 1. how light reflects from a mineral's surface, metallic or nonmetallic 4. inorganic solid material found in nature; two or more minerals make up rocks. 5. large cracks in Earth's crust 7. splitting of a mineral into pieces with smooth, regular surfaces that reflect light 9. the material moved by erosion 11. occurs when the minerals crystallize and "glue" the sediment together 13. living matter dies, piles up, and then in compressed into rock over millions of years 16. the process of pressing the sediments together 17. when agents of erosion lay down sediment and can change the shape of the land 19. rock that is produced when melted rock cools and hardens 20. a rare mineral that can be cut and polished 21. a type of rock made from pieces of other rocks, dissolved minerals, or plant and animal matter 22. test of which minerals scratch or are scratched by others; scale of 1-10

Down 2. process that occurs when natural forces move weathered rock and soil from one place to another 3. a solid material with a repeating pattern of atoms. 6. new rocks formed when existing rocks are heated and squeezed but not melted 8. any process that breaks down rocks and creates sediments; can be a chemical or physical/mechanical 10. made of grains of minerals or other rocks that have moved and been deposited in layers by water, ice, gravity, or wind 12. sedimentary rocks that form from mineral-rich water evaporating or other chemical processes 14. an ongoing process that describes how rocks change through natural processes from one type to another 15. the color produced when a mineral is scratched on an unglazed, white tile 18. compares the weight of a mineral with the weight of an equal amount of water
