  1. 2. Common sedimentary rock...made of grains of sand
  2. 5. A mixed forest region is an example of what?
  3. 7. This sedimentary rock is largely made up of the skeletal remains of shelled organisms etc.
  4. 11. Of all the factors which affect climate, which appears to have the single greatest impact?
  5. 12. These "currents" explain why plates move.
  6. 14. Process by which sediment becomes cemented into sedimentary rock
  7. 16. Geologist who came up with the theory of Plate Tectonics

  1. 1. The upward movement of water in a calcified soil profile.
  2. 3. The six factors which affect climate
  3. 4. Main reason why Tundra is the predominant vegetation type Canada's north.
  4. 6. Oil-rich landform region.
  5. 7. Ideal soil with a balance of silt, clay, sand and humus.
