| Question | Answer |
|---|---|
| What type of ocean water contain more dissolved oxygen? | Cold ocean water in polar regions |
| How do mussels adapt to changing tides near the shore? | They adapt by tightly closing their shells when the tide goes out |
| What is sonar? | A technique that uses sound waves to measure the depth of the ocean |
| What dissolved gas is added to ocean water as a result of photosynthesis? | Oxygen |
| Why are marine ecosystems so unique? | Marine ecosystems rely on many different abiotic and biotic factors like dissolved gases and phytoplankton for survival |
| What is an estuary? | The wide, lower course of a river where fresh and salt water mix |
| Why do plant plankton not grow in the deep ocean? | Because sunlight doesn't reach the deep ocean |
| How can species on the bottom of the ocean get energy to live without sunlight? | Hydrothermal vents produce energy through chemical reactions |
| What type of water is found in estuaries? | Brackish water |
| How does buoy technology assist coastlines worldwide? | It detects tsunami intensity, allowing for early evacuation of coastlines |
| What would happen to the ocean floor food web if plankton were not available? | All organisms that live in the ocean would not survive |
| What is the most abundant form of ocean life? | Microbes |
| What causes an increase in organic matter usually filtered by oysters in an estuary? | Over harvesting of oysters |
| Where can the richest deposits of oil and natural gas be located? | Continental shelves |
| What are the winds pushing water away from shore along the South American coastline? | Upwelling |
| What causes density currents? | Differences in salinity and temperature |
| What causes upwelling? | When wind causes surface water to move away from shore |
| How is the ocean the most diverse ecosystem? | It receives nutrients from land carried by rivers and upwelling |
| How did the invention of the Aqua Lung change scuba diving and marine exploration? | Divers could spend more continuous time underwater |
| What part of the ocean is the warmer and dissolved carbon dioxide is released back into the atmosphere? | At the surface |
| What invention allowed people to better perform research at ocean depths greater than 100 feet? | Submersibles |
| What is most effective in monitoring large areas of the ocean floor? | Satellites |
| What dissolved gases are most needed by plants and animals living in the ocean? | Oxygen and carbon dioxide |
| What is algal growth? | The largest source of dissolved oxygen in the ocean |
| Why is an estuary a good "nursery" area for marine organisms? | It had many areas to hide from predators |
| Why is productivity greatest near the ocean's surface? | Sunlight penetrates the top layers of the ocean, so photosynthesis occurs there |
| How would you describe the types of organisms found in estuaries? | They can tolerate both freshwater and salt water |
| What happens to nutrients in the ocean as a result of upwelling? | Upwelling carries nutrients to the surface of the ocean |
| Why is most of the oxygen in Earth's atmosphere produced in the top six inches of the oceans? | Oxygen is produced by photosynthesis microorganisms that live near the surface of the ocean |
| How would you describe the water distribution in an estuary? | Freshwater is closer to the surface than the saltwater |
| What is an estuary? | A nutrient rich salt marsh and mangrove Forest of the Florida Everglades |
| What would be the impact on the environment if there were no estuaries? | There would be more pollutants in the oceans |
| If a certain fish became the most popular fish used for sushi in Japan, how would this impact that species of fish? | Their numbers would decrease |
| What must organisms living in an intertidal zone be able to tolerate in order to survive? | Changes in both temperature and salinity |
| What natural feature protects inland bodies of water from contamination by salt water? | Estuary |
| Why must inhabitants of an estuary adapt to frequent environmental changes? | The salinity of the water is constantly changing |
