|---|---|---|---|---|---|
| Oceans cover | about 70 percent of the surface of Earth.
🗑
|
||||
| continental shelf | The area of seabed around a large landmass where the sea is relatively shallow compared with the open ocean.
🗑
|
||||
| continental slope | The slanting between the outer edge of the continental shelf and the deep ocean floor.
🗑
|
||||
| continental rise | A wide, gentle incline from an ocean bottom to a continental slope.
🗑
|
||||
| sediments | sand, mud, rocks.
🗑
|
||||
| Ocean trenches | are very deep.
🗑
|
||||
| is relatively shallow | continental shelf.
🗑
|
||||
| Ocean water is | a complex mixture of gases (air) and dissolved solids (salts, especially sodium chloride).
🗑
|
||||
| Marine organisms are dependent on | dissolved gases for survival.
🗑
|
||||
| The salinity of ocean water varies in some places depending on | rates of evaporation and amount of runoff from nearby land.
🗑
|
||||
| Salinity | Amount of salt in the ocean.
🗑
|
||||
| The basic motions of ocean water are | the waves, currents, and tides.
🗑
|
||||
| the Gulf Stream | caused by wind patterns and the differences in water densities (due to salinity and temperature differences).
🗑
|
||||
| mixing of ocean waters | can affect plant and animal populations.
🗑
|
||||
| Currents | affect navigation routes.
🗑
|
||||
| As the depth of ocean water increases, the temperature | decreases,
🗑
|
||||
| the pressure increases and the amount of light decreases | As the depth of ocean water increases
🗑
|
||||
| Plankton are | tiny free-floating organisms that live in water.
🗑
|
||||
| Animal-like plankton are called | zooplankton.
🗑
|
||||
| Plant-like plankton are called | phytoplankton
🗑
|
||||
| phytoplankton | carry out most of the photosynthesis on Earth.
🗑
|
||||
| photosynthesis from phytoplankton | provide much of Earth’s oxygen.
🗑
|
||||
| Phytoplankton form | the base of the ocean food web.
🗑
|
||||
| Plankton flourish in areas where | nutrient-rich water upwells from the deep.
