Across
  1. 2. inorganic crystalline substances found naturally in the earth
  2. 4. the "veins" of igneous rock that run in the same direction of the strata of the sedimentary rock
  3. 6. sand, silt, and other components of soil
  4. 9. the "veins" of igneous rock that run perpendicular to the strata of the sedimentary rock
  5. 10. layers
  6. 11. a surface of erosion that separates one layer of rock from another
  7. 12. unconformity an unconformity where the rocks below are tilted relative to the rocks above
  8. 13. separation between stratified layers and unstratified layers
  9. 17. the view that most of earth's geological features are the result of slow, gradual processes that have been at work for millions or even billions of years
  10. 18. several lamination layers formed right next to each other
  11. 20. the process by which sediments and rock fragments are carried away by wind or rain
  12. 23. a structure rising from the ground of a cavern formed by groundwater dripping and leaving sediment on the ground where it dripped
  13. 24. a structure formed in a cavern when a stalactite and a stalagmite meet and form a single structure
  14. 25. having a very sharp, geometric shape
  15. 27. an icicle-like structure hanging down from the ceiling of a cavern formed by groundwater dripping and leaving sediment on the ceiling
  16. 28. rock rock that forms from molten rock (magma, lava from volcanoes)
Down
  1. 1. the view that most of earth's geological features are the result of large-scale catastrophes such as floods, volcanic eruptions, etc.
  2. 3. unconformities where there are parallel, stratified rock layers above and below the unconformity, but a clear surface of erosion between them
  3. 4. rock rock that is formed from sediments which are laid down by water or some other agent and fuse together due to heat, pressure, and various chemical reactions
  4. 5. rock rock that has undergone extreme change due to lots of heat and pressure
  5. 7. arranged in layers
  6. 8. unconformities where geologists believe there is an unconformity but cannot identify it
  7. 14. open space underground where groundwater has eroded the rock
  8. 15. "veins" of igneous rock shooting right through several layers of sedimentary rock, formed when magma from underneath the sedimentary rock gets injected in the cracks of the sedimentary rock
  9. 16. a single layer of rock that is less than 1 centimeter (0.39 inches) thick
  10. 19. did not come from a living being
  11. 21. water that flows underground
  12. 22. the process by which rocks are broken down by the forces of nature
  13. 26. the decayed remains of once-living creatures
