| Question | Answer |
|---|---|
| 1. Concentration (concentración) | The proportion of a substance in a mixture (chemistry) -The amount of solute in a solution (related saturated) |
| 2. Thermal mass | The ability of an object to stay hot or cold (example - "ice packs" in a lunchbox) |
| 3. Diatoms (a type of plankton) | One of the family of microscopic unicellular algae - Remains (shells) of which are mined and used in many products |
| 4. Plankton (Plancton) | A generic term for all the microorganisms that float in the sea (from the Greek root that means "wanderer") |
| 5. SONAR | A device that uses sound (in the same manner as radar) to locate objects underwater (related echolocation)(think "Marco Polo") |
| 6. Salinity (salinidad) | The concentration of salt in sea water |
| 7. Water pressure (Presión de agua) | The amount of force that is applied over a given area divided by the size of this area- Caused by the weight of the water (related air pressure) - deeper down = greater pressure |
| 8. Gulf Stream (corriente de golfo) | The warm ocean current issuing from the Gulf of Mexico, flowing northeastwards along the Eastern coast of North America - warm water impacts the coastal climate and is rich in fish |
| 9. Continental Shelf (plataforma continental) | The area of sea around a land mass where the depth gradually increases before it plunges into the ocean deeps- most commercial fishing is done over this area |
| 10.Sea Mount (monte marino) | A mountain that rises from the floor of the ocean and does not breach the water's surface- If it reaches the surface is an island |
| 11. Mid Ocean Ridge (dorsal oceanica) | Sea-floor mountain range caused by spreading of plates |
| 12. Abyssal Plain (related plateau)(llanura abisal) | A large expanse of very flat and smooth ocean floor, (very deep) |
| 13. Continental Rise (elevacion continenental) | The steep slope at the bottom of the continental slope |
| 14. Continental Slope (talud continental) | The steep, narrow fringe separating the continental shelf from the continental rise |
| 15. Upwelling | Currents that bring water from the lower depths to the upper layers of the ocean; carries nutrients |
| 16. Tide pool | Ponds of ocean water that occur in the intertidal zone, important for many ocean organisms (intertidal - between low and high tide) |
| 17. Estuary (Estuario) | Partially enclosed water areas that are spawning (breeding) grounds for many ocean creatures |
| 18. a. 70-75% b. 50% | a. What is the percentage of Earth's surface covered by oceans? b. What is the percentage of O2 produced by phytoplankton? |
| 19. Artificial reef (filón artificial) | The use of old ships, subway cars, or other items to create a breeding niche for ocean creatures |
| 20. Salts in the oceans comes from rocks as rains dissolves the salts and carries it into the oceans. | Where does the salt in the oceans come from? |
| 21. Bonus questions - look it up! | What is a league? What is a Fathom? Who was/is Prince Dakkar? |
| 22. Mariana Trench (Mariana fosa abisal) | Deepest spot in the ocean, located at a subduction boundary |
| 23. Mediterranean Sea (Mar Mediterráneo) | Stretches from the from the Atlantic Ocean on the west to Asia on the east and separates Europe from Africa; connects with the Atlantic Ocean by the narrow and shallow channel of the Strait of Gibraltar; higher salinity than the open ocean |
| 24. Chesapeake Bay (Bahía de Chesapeake) | An important estuary / breeding ground for Blue Crab |
| 25. Coral reef (Filón coralino) | Colonies of tiny living animals that create large structures of calcium carbonate (think sea shells)- are found in warm waters and are very sensitive to pollution |
| 26. Limestone | A sedimentary rock formed from types of calcium carbonate - formed at the bottom of the ocean - often contains fossils of diatoms and other hard bodies sea organisms |
| 27. Tides (las mareas) | The daily raise and fall of the ocean level caused by the gravitation pull of the moon- spring tide is large / neap tide is small |
| 28. Marine | Having to do with oceans, seas, or boating |
| Temperature in deep parts of the ocean | Mostly cold, but some hot spots due to underwater volcanoes |
| 29. A. Why are the ocean environments important to mankind? B. What are some examples of how we are harming this environment? C. What can we do to protect this environment? | A- Production of oxygen, food, regulating climate and weather B- Chemical pollution from farms, lawns, roadways, and factories; garbage dumping C- Use chemicals responsibly, don't litter, recycle |
| 30. Zooplankton | Plankton that are animals |
| 31. Phytoplankton | Plankton that are plants |
| 32. Spawn | Eggs or young creatures - to give birth |
| 33. Brackish | Slightly salty water, such as in a bay - lower salinity than the ocean |
| 34. Barnacles | A marine crustacean that often attach themselves to boats, docks, or rocks |
| 35. Calcium | A mineral that is found in seashells, skeletons, and limestone |
| 39. Density | the "compactness" of a substance - the amount of "stuff" in a substance |
| 36. Convection | Heat transfer by motion in a fluid such as water or air - hot water or air expands, therefore they are less dense, and move upward |
| 37. Conduction | Heat transfer by direct contact - touch an ice cube - touch a hot object |
| 38. Radiation | Heat transfer through empty space - sunlight is an example |
