Question
Answer
The amount of dissolved salts in ocean water   Salinity  
🗑
Cause of ocean currents   winds and water density  
🗑
the most common source of energy for surface waves   wind  
🗑
the deepest parts of the ocean are these long, narrow crevices   trenches  
🗑
the gulf stream   a long distance surface current  
🗑
tides are mainly the result of the gravitational pull of...   moon  
🗑
the shallow and relatively flat part of the ocean floor where marine life flourishes   continental shelf  
🗑
the Earth's deepest ocean   Pacific Ocean  
🗑
the deepest spot known on Earth ....   Mariana Trench  
🗑
the percent of the Earth covered by water   71%  
🗑
a scientist who studies the ocean is an ....   oceanographer  
🗑
plantlike organisms that float on or near the ocean's surface are called...   phytoplankton  
🗑
ocean trenches are...   very deep  
🗑
the continental shelf is...   relatively shallow  
🗑
the beach where you swim and play is part of the...   continental shelf  
🗑
the salinity of ocean water depends on ....   rates of evaporation and runoff from nearby land  
🗑
the makeup of ocean water   a complex mixture of gases (air) and dissolved solids (salts, especially sodium chloride)  
🗑
underwater mountain ranges...   mid-ocean ridges  
🗑
the ocean floor near the continents (continental shelf, slope, and rise) is made of...   think layers of sediment (sand, mud, and rocks)  
🗑
a device that uses sound to map the ocean floor...   sonar  
🗑
motions of the oceans....   waves, currents, and tides  
🗑
ocean water can have different densities due to...   salinity and temperature differences  
🗑
producers of much of the Earth's oxygen....   phytoplankton  
🗑
as the depth of the ocean increases...   water pressure increases and the amount of light decreases  
🗑
the shoreline, where the land meets the ocean, is part of the...   continental shelf  
🗑
True or False: the shallow water of the continental shelf is teeming with life   true  
🗑
the steep slope at the edge of the continental shelf is...   the continental slope  
🗑
the deepest parts of the ocean are...   ocean trenches  
🗑
ocean trenches are deep...   deep canyons  
🗑
the wide, deep and flat mid-ocean bottom is the...   abyssal plain  
🗑
underwater mountain ranges are called...   mid-ocean ridges  
🗑
True of False: marine organisms are dependent on the dissolved gases in the ocean for survival   True  
🗑
ocean currents are caused by...   wind patterns, differences in water density caused by differences in water temperatures and salinity  
🗑
oceans flow like rivers in well defined circular patterns called...   currents  
🗑
the variation in water density and wind patterns cause ocean currents. colder water is likely to be (less/more) dense than warmer water. Water with (higher/lower) salinity is likely to be denser.   more / lower  
🗑
The Gulf Stream is one of the Earth's strongest currents. It moves north from the tropics through the Gulf of Mexico, past the east coast of the US and up to northern Europe. As a result, Europe is...   warmer than Canada at the same latitude  
🗑

🗑
phytoplankton are plantlike producers that get their energy...   from the sun  
🗑

🗑
most (90%) of marine organisms live in the   abyssal zone  
🗑
fishing line discarded in the ocean can...   cut and kill sea creatures  
🗑
salt in the ocean comes from...   the weathering of rocks and minerals  
🗑
a ____ is a river-like movement of water within a larger body of water   current  
🗑
what always increases as the ocean depth increases?   pressure  
🗑
what decreases as ocean depth decreases?   temperature  
🗑
what geological feature is crated by living organisms?   coral reef  
🗑
coral reefs, salt marshes, and estuaries are all...   marine habitat  
🗑
phytoplankton are...   plant-like plankton that get their energy from the sun  
🗑
the term "marine" in marine habitat, refers to...   salt water habitats  
🗑
