Across
  1. 4. process where dissolved minerals glue sediments together to form rock.
  2. 6. records- The total number of fossils discovered and the information they provide about Earth's history.
  3. 7. and cementation- Two steps in forming sedimentary rocks.
  4. 9. the process where forces inside earth push rock up to the surface.
  5. 10. rock found below Earth's surface.
  6. 12. when magma or lave hardens into igneous rock.
  7. 14. Solid rock becomes liquid magma due to high temperatures.
  8. 15. the movement of weathered rock or sediments by wind, water, or ice.
  9. 16. matter- Materials from once living organisms often of sediments.
  10. 18. cycle- the continuous process of rock formation and transformation between types.
  11. 19. and pressure- Conditions deep underground that change rock into metamorphic rock.
  12. 22. Rock- Rock formed when magma or lava cools and hardens.
  13. 23. Igneous Rock- Formed when lava cools quickly on Earth's surface.
  14. 25. fossil- A fossil- of an organism that lived for a short time but was widespread, used to help date rock layers.
  15. 26. The dropping of sediments in a new location.
  16. 29. Small pieces of rock, minerals, or organic materials.
  17. 30. The process where sediments settles in horizontal layers.
  18. 31. Lava that has reached Earth's surface.
Down
  1. 1. Igneous Rock- Formed when magma cools slowly beneath Earth's surface.
  2. 2. The general term for turning sediment into rock.
  3. 3. rock- rock formed from layers of sediments that are compacted and cemented together.
  4. 5. A naturally occurring solid substance with a definite chemical makeup and crystal structure.
  5. 8. Rock- Rock formed when existing rock is changed by heat and pressure.
  6. 11. time scale- A timeline that divides Earth's history into different periods based on fossils and rock layers.
  7. 13. breakdown of rocks into smaller particles by wind, water, ice, or biological activity.
  8. 17. The formation of crystals as magma or lava cools.
  9. 20. Dating- Determining the exact age of a fossil or rock using radioactive elements.
  10. 21. The process of pressing sediments together under pressure.
  11. 24. The way organisms are protected and remains intact in the rock record.
  12. 27. dating- Determining the age of a rock layer compared to others.
  13. 28. Preserved remains or those of living organisms from the past.
