| 97% | how much saltwater there is on Earth |
| waves | wind causes these in the ocean |
| gravitational pull of moon | causes the tides |
| decreases | what happens to the temperature as you descend through the water column |
| increases | what happens to density and pressure as you descend through the water column |
| currents | caused by a river or stream moving through a body of water |
| differences in density | deep ocean currents are caused by |
| coriolis effect | causes ocean currents to curve to the right or left |
| salinity | measure of salt content in water |
| sonar | sound waves |
| abyssal plain | flat part of ocean floor |
| seamount | formed by under water volcanos |
| volcanic island | formed by under water volcanos |
| mid ocean ridge | range of mountains in the ocean |
| neritic zone | the part of the ocean that extends from low-tide to the continental shelf |
| intertidal zone | part of the ocean that extends from high tide to the point on the contiental shelf exposed by the lowest low tide |
| affects the size of a wave | strength, lenght of time, distance |
| what happens to wave height as it nears the shore | increases |
| what happens to wavelenght as it nears the shore | decreases |
| tsunami | under ocean earthquakes |
| rip-current | a rush of water that flows rapidly back to sea through a narrow opening |
| dunes | reduce beach errosion |
| stop sand movment | why dunes reduce beach errosion |
| evaporation | increases the salinity of sea water |
| algae | carry out photosynthesis |
| oxygen | gas released into the ocean through photosynthesis |
| tides | daily rise and fall of water on Earth's coastlines |
| force of sun and moon on earth | gravity |
| trench | place where greatest amount of water pressure is located |

| What is "E"?, | trench |
| spring | when the greatest difference in tides occurs |
| upwelling | when cold water rises up |
| intertidal | area of shore that is underwater during high tide and exposed during low tide |
| where wouldl the greates pressure be felt | trench |
| gulf stream | a large powerful warm surface current in the Atlantic |
