Ocean and the Climat
| Question | Answer |
|---|---|
| What events occur as a result of upwelling? | Surface currents flow away from the shore. The California Current moves water south from the North Pacific. Plants get the mineral they need for photosynthesis. |
| Measure of the amount of dissolved salts in seawater. | salinity |
| Technique that directs sound waves toward the ocean floor at an angle to map its topography. | side-scan sonar |
| Current caused by wind | surface current |
| Set of data that plots changing water temperature with depth | temperature profile |
| Current cause by differences in the temperature and salinity of ocean water. | density current |
| Level of the ocean's surface | sea level |
| Transitional layer of the ocean characterized by rapidly decreasing temperatures with depth. | thermocline |
| At what depth is the color red visible? | 25 meters |
| Why would it be beneficial for a deep sea creature to be the color red and not blue? | blue is visible at greater depths so they would be more visible for predators. |
| What three factors control surface currents? | global winds, the Coriolis effect, and continental deflection |
| How does the gulf stream current affect the temperature of coastal climates? | It makes them warmer. |
| How does the California current affect the climate for coastal cities in California? | It makes them cooler. |
| Closed, circular current system | gyres |
