Across 3. Change form 5. mineral grains are flattened and line up in parallel bands 7. made from magma/lava high in silica and oxygen. Rocks are light-colored. 10. Formed from sediments (rock fragments, mineral grains, animal & plant remains-shells, bones, leaves, stems) that are pressed or cemented together or when sediments precipitate out of a solution. 11. Usually have LARGE crystal grains (they cooled slowly) Cooling could have taken hundreds of years. 12. Made of the mineral halite. 13. Remains of swamp plants buried in water or by volcanic ash. 14. No bands are formed 15. occurs when wind or water of erosion lay down sediment.

Down 1. made from lava/magma that is low in silica, rich in iron and magnesium. Rocks are dark-colored. 2. ade of broken pieces of other rocks. Formed when rock fragments are squeezed together. 4. Usually have SMALL or NO crystals (they cooled too quickly) 6. remains of plants and animals are deposited in thick layers 8. The most abundant type of rock 9. earth materials change back and forth among the different types of rocks
