Across
  1. 2. Solid substances that are present in nature and are comprised of one or more chemical elements
  2. 5. Rocks that are from particles of sand, shells, pebbles, and other fragments of materials. These rocks are formed from compacted sediment as layers accumulate over time
  3. 11. the top layer of the Earth's surface
  4. 12. True or False fossils are rocks
  5. 13. Rocks that are formed when magma cools and hardens. This can occur inside or outside the Earth's surface. These rocks often look shiny or glasslike and may have tiny holes from the cooling process
  6. 14. the solid layer of earth that is comprised of the crust and the upper portion of the mantle
  7. 16. when two plates collide
  8. 17. when two plates slide past each other horizontally
Down
  1. 1. the ratio of a mineral's mass to its volume
  2. 3. below the lithosphere making it hotter and slush-like
  3. 4. Rocks that are formed under the surface of Earth due to heat and pressure. These rocks often have ribbon-like layers and shiny crystals
  4. 6. the result of chemical and mechanical processes that break down rocks
  5. 7. Deltas are mainly created by the process of
  6. 8. when two plates move apart
  7. 9. the movement of rocks and soil
  8. 10. the layer of hot solid material between Earth's crust and core
  9. 13. dense sphere of solid iron and nickel at the center of earth
  10. 15. a layer of molten iron and nickel that surrounds the inner core of earth
