Across
  1. 4. a fragment of a mineral crystal or a rock
  2. 6. rock that is formed when pre-existing rock changes into new rock as a result of an increase in pressure and temperature
  3. 8. this type of rock is a rock which contains the raw materials from which hydrocarbons eventually form
  4. 9. a type of unconformity at which sedimentary rocks overlie older intrusive igneous or metamorphic rocks
  5. 11. a boundary at which one lithospheric plate slips laterally past another
  6. 13. the study of the Earth, including our planet’s composition, behavior, and history
  7. 14. a fold with an arch-like shape in which the limbs dip away from the hinge (Opposite of syncline)
  8. 15. a tabular intrusion of rock that cuts across the layering of country rock
  9. 17. the compass orientation of a horizontal line on a plane
  10. 18. the grinding away and removal of the Earth’s surface materials by moving water, air, or ice
  11. 21. a bend or wrinkle of rock layers or foliation
  12. 22. this type of boundary is when two plates move apart from one another
  13. 23. molten rock that has flowed out onto the Earth’s surface
  14. 24. a large, cone-shaped subaerial volcano consisting of alternating layers of lava and tephra
  15. 26. igneous rock that is formed by the freezing of magma underground
  16. 27. rock that forms when hot molten rock cools and freezes solid
  17. 30. a magnetic field with a north and south pole, like that of a bar magnet
  18. 33. the thick layer of rock below the Earth’s crust and above the core
  19. 34. an accumulation of loose mineral grain, such as boulder, pebbles, sand, silt, or mud, that are not cemented together
  20. 36. the rock that makes up the outermost layer of the earth
  21. 37. molten rock that is below the surface
  22. 38. the point on the surface of the earth directly above the focus of the earthquake
Down
  1. 1. a trough-shaped fold where limbs dip towards the hinge
  2. 2. the resistance of material to flow
  3. 3. the way a mineral surface scatters light
  4. 5. the release of lava and/or pyroclastic debris from a volcanic vent
  5. 7. a streamlined block of rock ejected from a volcano
  6. 10. the process by which one oceanic plate bends and sinks down into the asthenosphere beneath another plate
  7. 12. the systematic study of natural phenomena via observation and, computation, experiment, and modeling
  8. 13. water that resides under the surface of the Earth, mostly in pores or cracks of rock or sediment
  9. 16. the process by which sediment settles out of a transportation medium
  10. 19. the process by which continental lithosphere stretches horizontally and thins vertically
  11. 20. a vast composite, intrusive, igneous rock body formed by the intrusion of numerous plutons in the same region
  12. 23. a sudden movement of rock and debris down a nonvertical slope
  13. 25. the series of smaller earthquakes that follow a major earthquake
  14. 28. a vibration caused by the sudden breaking or frictional sliding of rock in the Earth
  15. 29. a boundary between two different rock sequences representing an interval of time during which strata were not deposited and/or eroded
  16. 31. mountain building event
  17. 32. this type of plate boundary is when two plates move towards one another and one subsides under the other
  18. 35. an unconformity in which the strata below were titled or folded before the unconformity developed; strata below the unconformity therefore have a different tilt than strata above
