Top layer which is about a meter deep
What is nueston zone
100
Animals that live in this zone have adapted to survive the exposure to air. (Herons, Sear Stars, Periwinkle snails)
What is intertidal zone?
100
This type of surface current transports 25 more water than all the rivers in the world.
What is gulf stream?
100
Salinity is measured in what units.
What is PPT (parts per thousand)?
100
The farthest depth at which a scuba diver can safely explore.
What is 40 meters?
200
The ocean is divided into layers, what 3 factors are used to determine different ocean layers.
What is heat, light and salinity?
200
The ocean floor. The deepest parts do not get any sunlight and it is very cold.
What is benthic zone?
200
Two natural factors that influence surface currents.
What is global winds, the Coriolis effect and continental deflections.
200
Name the three main gases that are dissolved in ocean water.
What are nitrogen, oxygen and carbon dioxide?
200
Name the world's oceans.
What is Pacific, Atlantic, Indian, Arctic, and Southern.
300
Suitable habitat for living creatures because of the warmth and light from the sun's rays. About 100 meters deep.
What is surface zone?
300
Moving away from the shore, the water becomes deeper, and the ocean floor begins to slope downward.
What is neritic zone?
300
The density of water is affected by what two factors?
What is salinity and temperature?
300
Name three dissolved solids that can be found in the oceans. Which one is most abundant?
What are sodium chloride (sodium and chlorine), magnesium, sulfer, calcium, potassium? Must abundant: Sodium Chloride
300
Largest producer of oxygen in the Oceans
What is phytoplankton?
400
This zone ends where significant photosynthesis can no longer occur.
What is twilight zone?
400
In this zone, the sea floor drops sharply. This zone contains the deep water of the open ocean.
What is oceanic zone (pelagic)?
400
When cold, nutrient rich water from the deep ocean rises to the surface and replaces warm surface water.
What is upwelling?
400
The measure of the amount of dissolved solids in a given amount of liquid.
What is salinity?
400
T/F- Gasses dissolve easier in warm water than in cold water.
What is false.
500
Largest zone, 75% of the average ocean depth.
What is dark zone?
500
A very important area where fresh water from the rivers and the salt water from the oceans are always mixing.
What is estuary?
500
The earth's rotation causes winds and surface currents to move in curved paths rather than in straight lines. Explain the difference in the wind patterns between the northern and southern hemisphere
What is coriolis effect. Southern hemisphere- left, northern hemisphere- right.
500
Coastal water in places that have hot, dry climates have a ___________ (high/low) salinity.
What is high?
500
Explain the differences in temperature, light, and pressure as you descend downward into the ocean.
What is temperature decreases, light decreases, and pressure increases?
