| Question | Answer |
|---|---|
| the horizontal distance between wave crests | wavelength |
| the lowest point of the wave | trough |
| the highest point of the wave | crest |
| the size of the wave is NOT affected by | the salinity of the water |
| what are the 3 parts of the continental margin | shelf, slope, rise |
| holds oil, gas, sun, and nutrients. lots of life | shelf |
| holds submarine canyons and has a strong turbidity current. very steep | slope |
| what are the 3 parts of the open ocean | sunlit zone, bathyl region, abyssal region |
| what are the 4 major oceans | Indian, Pacific, Arctic, Atlantic |
| as a wave nears shore, the wave height increases and and the wavelength | decreases |
| when a tsunami hits shore, it can be very destructive because of its large | wave hieght |
| in which ocean are tsunamis most common | pacific |
| a rush of water that flows rapidly back to sea through a narrow opening is called | rip current |
| to reduce erosion along a strip of beach americans build a wall of rocks called | jetty |
| tides are caused by | gravity |
| this is caused when the earth the moon and the sun are in line and causes an extremely high tide | spring tide |
| extremely low tide | neap tide |
| salinity is a measure of what in water | dissolved salts |
| what is the most abundant salt in sea water | sodium chloride |
| which of the fallowing areas in the ocean is likely to have the lowest salinity | a bay at the mouth of a river |
| the densest ocean water is generally found | in the deep zone |
| a large stream of moving water that flows through the oceans is called | a current |
| what is an example of a current | longshore drift |
| the movement of cold deep ocean water to replace the warm water at the surface is called | upwelling |
| a technique that uses sound waves to measure the depth of the ocean floor | sonar |
| deep canyon in the ocean floor | trench |
| organisms that live in the ocean floor | benthos |
| organisms that have the ability to swim and live throughout the water colomn | nekton |
| many organisms that live in the intertidal zone are adapted to cling to the rocks to withstand | the crashing of waves |
| as the ocean water in a tidal pool warms and evaporates, the remaining water becomes | saltier |
| the part of the ocean that extends from from the low tide line to the edge of the continental shelf | neritic zone |
| organisms that form the base of the food chain | phytoplankton |
| what is a living resource from the ocean | algae |
| richest deposits of oil and natural gas are usually found on the | continental shelf |
| organisms that make light without heat | bioluminescent |
| nearly flat region of the ocean floor | abyssal region |
