  1. 1. An ion that is made up of more than one atom from the periodic table. Example: carbonate
  2. 5. The number that tells us how many protons or electrons an atom has.
  3. 10. Blood vessel that carries deoxygenated blood back to the heart. Thin muscle and elastic tissue with a large lumen.
  4. 11. The main artery carrying blood to all parts of the body.
  5. 12. Plate boundary where two tectonic plates are sliding sideways past each other.
  6. 14. The unit for resistance.
  7. 18. The unit for power.
  8. 19. The breaking down of rocks into smaller pieces.
  9. 20. a rock that forms from compressed or cemented layers of sediment building up on top of each other.
  10. 22. The unit for power.
  11. 24. The smallest type of blood vessel that delivers oxygen and glucose to the cells. One cell thick blood vessel.
  12. 25. A massive layer of very hot rock beneath the Earth's crust.
  13. 26. Underground location of the fracture in the crust that causes an earthquake.
  14. 28. The number that tells us how many protons plus neutrons an atom’s nucleus has.
  15. 29. A substance which releases hydrogen ions (H+).
  16. 30. New Zealand lies on the Indo-Australian plate and the ....... plate.
  17. 31. Cells that are responsible for clotting blood for injuries.
  18. 32. Scale used to assess how much energy is released during an earthquake.

  1. 2. A type of rock that forms from the cooling of molten rock at or below the surface.
  2. 3. A large vein that carries deoxygenated blood from the body to the heart.
  3. 4. An electric circuit where the components are connected in multiple loops.
  4. 6. Plate boundary where plates are moving towards each other and colliding.
  5. 7. A type of rock that forms from an existing rock that is changed by heat or pressure.
  6. 8. A material that does not allow electrons / electric current to flow through it.
  7. 9. Movement of a large amount of liquid or gas. Hot particles rise & cold particles sink.
  8. 13. Plate boundary where plates are moving apart, resulting in new crust being formed in between.
  9. 15. A substance which releases hydroxide ions (OH-).
  10. 16. Type of blood vessel that carries oxygenated blood AWAY from the heart. Thick muscle and elastic tissue with small lumen.
  11. 17. A positively charged ion. The positive charge is from the loss of electrons.
  12. 20. A volcano with broad, gentle slopes. Its lava has a low viscosity. E.g. Banks Peninsula
  13. 21. A negatively charged ion. The negative charge is from the gain of electrons.
  14. 23. The electrons in the outermost shell of an atom.
  15. 27. The transport of broken-down material.
