The total amount of dissolved salts in sea water.
Salinity
100
These are the three categories of life in the ocean
Plankton, neckton, benthos
100
Any disturbance that transfers energy through matter or empty space is called a _____________
wave
100
This zone gets the most sunlight
Euphotic zone
100
Ocean water is colder at __________ latitudes
high
200
Adding salt or _______________ solids to water changes the salinity of the water.
dissolved
200
Name any specific animal that is neckton
Answer varies (any animal that can freely swim in the ocean)
200
The highest point of a wave is called the ____________ and the lowest point is called the _______________
crest, trough
200
The zone closest to shore
Intertidal zone
200
At this "line", water no longer drops in temperature with depth.
Thermocline
300
Precipitation and river and stream run-off (increases / decreases) salinity.
decreases
300
These are the smallest type of animal in the ocean
Zooplankton
300
The amount of time it takes a wave to pass a fixed point.
wave period
300
Open ocean of any depth
Pelagic Zone
300
Why is there no thermocline at high latitudes?
Because there is so little sunlight, the surface water is just as cold as deep waters.
400
Water removal processes such as evaporation and freezing _________________ the salinity of the water.
increase
400
These organisms are at the very base of the entire ocean food web
Phytoplankton
400
What force causes most ocean waves?
Wind moving over the surface of the water
400
Where the aphotic zone starts
(about) 100 meters
400
Define pynocline
The area of ocean water where there is a rapid change of density with depth
500
The ___________ of ocean water depends on temperature and salinity.
Density
500
Tube worms fall under this category of life in the ocean
Benthos
500
Name 2 factors (besides wind) that can cause ocean waves.
earthquakes, volcanoes, landslides, meterorites/asteroids...
500
The difference between the benthic zone, and abyssal zone
The benthic zone is any and all ocean floor. The abyssal zone is a subdivision that includes only the deep ocean floor.
500
Explain how sea ice can both increase and decrease salinity
Increase: When sea ice forms, only the water freezes, leaving behind salt and making the surrounding the waters saltier Decrease: When sea ice melts, it releases water into the ocean, decreasing salinity
