  1. 6. escape of molten rock (magma) at the Earth's surface
  2. 8. magma that erupted and is now above ground
  3. 12. when magma hardens above ground to form...
  4. 17. when the earth's surface layers begin to slant irregularly
  5. 18. ground shaking caused by the energy that is released when rock on either side of a fault suddenly moves.
  6. 20. bending of rock layers caused by compression of rocks, usually as part of mountain-building when tectonic plates collide.
  7. 22. when heat is added to a solid and turns to a liquid.
  8. 23. process by which a solid forms, where the atoms or molecules are highly organized into a structure.
  9. 24. high temperature
  10. 25. crushed or compressed
  11. 26. formed from magma rock hardening
Down
  1. 1. any trace of past life preserved in a rock (includes animal tracks & burrowsas well as shells, skeltons and impressions of soft flesh).
  2. 2. material deposited by water, wind or ice. Includes pebbles, sand, mud, organic remains (e.g.shells) and salts left by evaporation.
  3. 3. Opening through which lava and rock fragments erupt, usually within a volcanic crater.
  4. 4. deep cracks caused by movement of rock during earthquakes. Different rock types are often seen on each side of a fault.
  5. 5. the washing away of land from water.
  6. 7. continuous physical force exerted on or against an object by something in contact with it.
  7. 9. sediments, soil and rocks are added to a land form or land mass.
  8. 10. process of deposition of a solid material from a state of suspension or solution in a fluid
  9. 11. sediments are glued together by minerals that are deposited by water.
  10. 13. when a region is literally lifted up as the crust is squeezed by tectonic forces or, sometimes, following the melting of ice-sheets.
  11. 14. physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form.
  12. 15. the release of water from plants.
  13. 16. breakdown of rocks at the Earth's surface, by the action of rainwater, extremes of temperature, and biological activity.
  14. 19. temperature drop
  15. 21. when magma hardens under ground to form...
