Ocean Currents
This force caused by Earth’s rotation makes ocean currents curve around the planet.
Coriolis Effect
This is the top layer of the ocean where sunlight penetrates.
The Epipelagic (or Sunlight) Zone
These microscopic organisms form the base of most ocean food webs.
Phytoplankton
This is the depth of the Mariana Trench, the deepest part of the ocean, in meters.
About 11,000 meters.
This property of seawater increases as the amount of dissolved salts rises.
Density of the water.
These two main factors—alongside wind—drive surface ocean currents.
Temperature and Salinity(salt content)
This is the deepest ocean zone, found in ocean trenches.
Hadal Zone
Energy transfer in food webs is inefficient—only about ____ percentage moves from one level to the next.
10%
This is the only ocean considered to be entirely warm.
Indian Ocean
The lowest point on earth (not in the ocean) is: _________________? How many meters below sea level?
the Dead Sea -430m
This warm current flows along the eastern coast of the United States.
The Gulf Stream
This dark zone extends from 200 to 1,000 meters deep.
Mesopelagic (or Twilight) Zone
These small animals drift in the water and feed on phytoplankton.
Zooplankton
This mountain, the highest in altitude (above sea level). What is the name and hight (m)?
Mount Everest (8849)
This process, where water changes to vapor, leaves salts behind and increases ocean salinity.
Evaporation
Which Ocean Current brings cold water up from the Antarctic to the tip of South Africa (greatest country ever ;-))?
Cape Aghulas
This zone, from 1,000 to 4,000 meters deep, is completely dark and very cold.
The Bathypelagic Zone (Midnight).
In the ocean food web, sharks are considered this type of consumer.
Apex Predators
This is the name of the tallest underwater volcano and how tall is it (m)?
Mauna Kea (10,100m)
In polar regions, this process removes freshwater and increases the surrounding ocean’s salinity (saltiness).
Freezing (creation of sea-ice)
What is the name given to the phenomenon whereby hot water (or air) rises and cold water (or air) sinks.
Convection
Which Ocean zone would have the least producers (organisms making food)?
Hadal Zone (the bottom zone), because there is no sunlight down there to bring the energy to this layer. Virtually all animals are consumers.
Which organisms are responsible for creating up to 70% of the earths oxygen?
Phytoplankton
One can find sea-shells at the top of Mount Everest. Why? (most scientifically correct answer gets the points - judged by Mr Müller)
Continental Drift Theory - India (subcontinent crashed into Asia)
Was the ocean more saline (salty) or less saline (salty) 500 million years ago? Why?
Less, more minerals have been added to the sea since.
