- 3. What creatures are the foundation of the marine food web, feeding everything from anchovies to whales?
- 6. The oceans of the world have absorbed about this much percentage of all the CO2 produced by burning fossil fuels.
- 8. one northern, one southern,There are this many deep currents coming to the Oregon coast from Japan...
- 9. To change from a liquid to a gas.
- 10. A phase in which matter has no definite shape or volume. o It will expand to fill any container. It can also be compressed. o Molecules in this phase are relatively far apart and move freely. o Water in this phase is called water vapor
- 15. The temperature at which freezing occurs. At sea level, it is 0 °C (32 °F) for pure water. (Two words, no space).
- 17. What is the universal solvent?
- 21. By decreasing the amount of oysters through ocean acidification, these are the groups most harmed by the loss of this *crop*... (Two words, no space).
- 24. Corals are important in the ocean food chain because this percentage of other ocean creatures live in coral reefs... (Three words, no space).
- 27. This is the source of and primary reason for the oceans becoming more acidic. (Three words, no space).
- 30. Having a pH of exactly 7.0
- 31. pH less than 7 and more H+ ions
- 32. How much more acidic has the ocean become since humans began producing so much CO2 (mostly in cars and factories)? (Two words, no space).
- 36. The ocean chemistry is identified as an *early impact* area along this region of coastline because the ocean chemistry is changing so rapidly here...
- 37. The water off the Oregon coast is actually coming there from...
- 39. A phase in which matter has definite volume but no definite shape. o It will take the shape of a container but cannot expand or be compressed. o Molecules in this phase move randomly but stay close to one another.
- 40. To change from a liquid to a solid.
- 41. point,The temperature at which melting occurs. o At sea level, this is 0 °C (32 °F) for pure ice.
- 42. A phase in which matter has a definite shape and a definite volume. o This phase will retain the same shape and volume in any container. o Atoms in this are held in a rigid structure and cannot move freely. o Water in this phase is called ice.
- 43. How much CO2 do phytoplankton pull out of the atmosphere ever year? (Two words, no space).
- 44. Phytoplankton absorb about as much of this global warming molecule as all of the worlds land plants combined... (Two words, no space).
- 45. These are the microscopic *plants* of the sea that can use sunlight and photosynthesis to soak up CO2 reduce the effects of ocean acidification.
Down
- 1. This is a mixture that has small undissolved particles that do not settle out and cannot be easily separated. Milk is this.
- 2. This is a uniform mixture that contains a solvent and at least one solute
- 4. The water off the Oregon coast is an upwelling current coming up from the deep that is carrying the CO2 signature of this many years ago because thats how long ago it was last at the surface. (Two words, no space).
- 5. This greenhouse gas molecule in the atmosphere is increasing as a result of burning fossil fuels, causing global temperatures to increase. (Two words, no space).
- 7. This is a mixture in which the particles can be seen and easily separated by filtering or settling out. Pepper in water is this.
- 11. An atom or atoms with a positive or negative charge.
- 12. The temperature at which boiling occurs. At sea level, it is 100 °C (212 °F) for pure water. Water boils at lower temperatures at higher altitudes because air pressure is lower there. (Two words, no space).
- 13. This is the part of the solution that is present in large amounts and dissolves other substances. Usually it is liquid.
- 14. In sea water is CO2 the solvent or the solute?
- 16. having a pH greater than 7 or more OH- ions
- 18. What are the two ions made from carbon dioxide in Monterey Bay? One makes acid sea water and the other makes shells for creatures. (Two words, no space).
- 19. To change from a solid to a liquid
- 20. In just a few decades the oceans may be more acidic than they have ever been in the last __________ years? (Two words, no space).
- 22. When CO2 reacts with sea water this harmful ion is produced that makes the oceans more acidic. (Two words, no space).
- 23. A state of matter with certain physical properties. o Solid, liquid, and gas are this and occur naturally on Earth. o Plasma is this found in stars.
- 25. This is the molecule in sea water that creatures like clams and corals use to build their shells.
- 26. It is the part of the solution that is present in smaller amounts and is dissolved by the solvent. Usually a solid to start out with.
- 28. Does a warming ocean or a cooling ocean absorb less CO2?
- 29. There is a narrow window of this many hours in the early life of the oyster larvae during which the presence of Carbonate ion (CO3-) must be high (and Hydrogon ion H+ is low) in order for the oyster crop to be viable and produce many baby oysters. (Two words, no space).
- 33. If we stopped producing all CO2 today, the ocean acidification will be continuing to increase off the Oregon coast for this many more years as the deep current continues to make it's way across the Pacific... (Three words, no space).
- 34. How much of the planets yearly oxygen production is generated by phytoplankton? (Two words, no space).
- 35. When we say that the oceans are becoming more acidic through adding CO2 we are really saying that there is ___________ pH in the ocean than before.
- 38. This is the planet's biggest "carbon sink".
