Across
  1. 1. The mechanical breakdown of rocks and minerals
  2. 3. The breakdown of rocks and minerals by chemical reactions, the dissolving of chemical elements from rocks, or both
  3. 5. Rock that forms when sedimentary rock, igneous rock, or other metamorphic rock is subjected to high temperature and pressure
  4. 7. Rock formed directly from magma
  5. 12. rock Rock that forms when magma cools above the surface of Earth
  6. 15. A vent in the surface of Earth that emits ash, gases, or molten lava
  7. 16. An area where tectonic plates move sideways past each other
  8. 17. The formation of new ocean crust as a result of magma pushing upward and outward from Earth’s mantle to the surface
  9. 21. In geology, a crack that occurs in rock as it cools
  10. 22. A large expanse of rock where a fault has occurred
  11. 23. The frequency and intensity of earthquakes experienced over time
  12. 24. A place where molten material from Earth’s mantle reaches the lithosphere
  13. 25. The process of one crustal plate passing under another
Down
  1. 2. The layer of Earth located in the outer part of the mantle, composed of semi-molten rock
  2. 4. The innermost zone of Earth’s interior, composed mostly of iron and nickel. It includes a liquid outer layer and a solid inner layer
  3. 5. The layer of Earth above the core, containing magma
  4. 6. An area beneath the ocean where tectonic plates move away from each other
  5. 8. Rock that forms when sediments such as muds, sands, or gravels are compressed by overlying sediments
  6. 9. The outermost layer of Earth, including the mantle and crust
  7. 10. An area where plates move toward one another and collide
  8. 11. A scale that measures the largest ground movement that occurs during an earthquake
  9. 13. rock Igneous rock that forms when magma rises up and cools in a place underground
  10. 14. Precipitation high in sulfuric acid and nitric acid from reactions between water vapor and sulfur and nitrogen oxides in the atmosphere
  11. 18. In geology, the chemically distinct outermost layer of the lithosphere
  12. 19. Molten rock
  13. 20. A fracture in rock caused by a movement of Earth’s crust
