|---|---|
| "mini" ocean; salty like oceans | seas |
| land underwater that border continents | continental margins |
| holds oil and natural gas; a lot of ocean life is here | continental shelf |
| the dramatic drop off | continental slope |
| deepest depression that holds the earth's water | ocean basin |
| long narrow openings in the ocean floor; the deepest part of the ocean | trenches |
| the ocean floor that is flat and most level | abyssal plain |
| under water volcanoees | sea mounts |
| rock like structures formed in shallow water by colonies of tiny sea animals; shell like part of body left behind | coral reef |
| ring shaped coral reef that is surrounded by a body of water and is attached to an under water volcano | atoll |
| water flows but moves slower | waves |
| a breaking wave circles to ellipse - water slows and wave heightens - top becomes very heavy | breaker |
| when wave breaks in open sea due to strong winds | white caps |
| the size of the wave is not affected by the... | salinity of the water |
| a rush of water that flows rapidly back to sea through a narrow opening is called a... | rip current |
| to reduce erosion along a strip of beach, you might build a short wall called a.... | groin |
| jetti | rock wall version of groin |
| dunes reduce beach erosion because | the roots of the dune plants hold the sand inplace |
| tides are caused by | the inter action of the earth, moon, and sun's gravity |
| salinity is the measure of | dissolved salts |
| what is the most abundant salt in the sea water | sodium chloride |
| which area in the ocean will have the least salinity | a bay at the mouth of a big river |
| the densest water is generally found in the | deep zone |
| a large stream of moving water that flows through the oceans is called a | current |
| the movement of cold water to replace warm water at the surface | upwelling |
| a technique that uses sound waves to measure the depth of the ocean foor | sonar |
| what does not make studying the ocean floor difficult | salinity of the water |
| a deep canyon in the floor | trench |
| benthos live on | the continental shelf |
| an example of a nekton is | a dolphin |
| organisms that live in the rocky intertidal zone are adapted to cling to the rocks to withstand the | pounding of the waves |
| as the ocean water in a tide pool evaporates the water become | saltier |
| the part of the ocean that extends from the low tide line to the edge of the continental shelf is the | neritic zone |
| the organisms that form the most open-ocean food webs are | plankton |
| organisms that produce their own light | bioluminescent |
| the area that stretches down the highest tide line on land out to the point on the continental shelf exposed by the lowest low tide is called the | intertidal zone |
| the neritic zone is part of the ocean located above the | continental shelf |
| tsunamis are caused by | earthquakes |
| a wall of rocks built outward from a beach is called a | jetti |
| the daily rise and fall of earth's coastlines are called | tides |
