Across
  1. 2. when a sudden release of energy in the lithosphere creates seismic waves
  2. 4. Water held underground in the soil in deep reservoirs
  3. 8. move througho side trough only solids. travels slower than p waves
  4. 12. spot When magma flows through a crack in the middle of a tectonic plate, and not a plate boundary. Hawaiian islands were formed this way.
  5. 13. A tool that measures/records details of earthquakes
  6. 18. boundary the tectonic plates slide past each other
  7. 19. innermost the intermostthe layer of earth. divided into 2 parts, liquid outer and solid inner. made of iron and nickel.
  8. 20. the supercontexistedhat exsited before continents separated
  9. 21. forms when mcrystallizescrystalizes and solidifies. Appears glassy
  10. 22. is the outer part of the earth. Includes the crust and upper mantle
  11. 24. formpre-existingxsiting rock and fossils.appears layered
  12. 26. A solid inorganic material founfossil fuel uel Petroleum, natural gas, coal. made from remains of plants and animals
  13. 28. the lower part of the earth´s mantle, below the asthenosphere
  14. 29. is the movement caused within a fluid when the hotter,less dense material rises, and colder, denser material sinks
Down
  1. 1. below the lithosphthe ere, hotter and more fluid part of the mantle
  2. 3. cycle When h eat, pressure,cooling, melting, and weathering cause rocks to change from one type to another over time
  3. 5. boundaryy boundry where the tectonic plates divide
  4. 6. occurs when divergent plseparateerate. convection currents cause less dense material to rise. creates new ocean floor
  5. 7. form at convergent boundaries where one plate subducts under another, and magma underground is pushed upward.
  6. 9. group of animals that occupy a certain area
  7. 10. seafloor spreading dary where the tectonic plates collide
  8. 11. solid is the sthe loid, outermost layer of the earth, lying above the mantle
  9. 14. still in existence, surviving species
  10. 15. forms under extreme heat and pressure. appears twisted
  11. 16. is the the study of earth
  12. 17. the layer thathe t lies between earth´s crust and core. the majority of earth mass is in this layer
  13. 23. the study of earthquakes and related phenomena
  14. 25. compresthroughqueeze trough solids and liquids. travels faster than s waves
  15. 27. plates largof pieces a lithosphere that the ocean and continents rest on
