Unique Nature of Pure Water
This molecule has two atoms of hydrogen and one atom of oxygen chemically bounded together.
What is water?
This penetrates the deepest while the other colors are absorbed
What is blue light?
The total amount of salt dissolved in water
What is Salinity?
Respiration by consumers, decomposers and producers make this element available again.
This is the first layer and is most commonly called the Sunlight Zone.
What is the Epipelagic Zone?
The sticking together of particles of the same substance.
What is cohesion?
Animals like fishes, marine mammals, and shrimps use this for communication, reproduction, and predator and prey detection.
What is sound?
Temperature in the ocean varies more than salinity; so density is controlled more by ______ than salinity.
What is Temperature?
These are needed by organisms to build and maintain shells and other calcium carbonate structure.
What are carbonate ions?
This zone is known as the Trenches, the temperatures are very cold.
What is the Hadalpelagic zone?
The amount of heat needed to raise a substance‘s temperature by a given amount
What is heat capacity?
Used to measure water clarity
What is a Secchi Disk?
Variations to ocean salinity are usually the result of the addition or removal of _____
What is pure water?
Through this process carbon dioxide is converted into organic compounds (glucose).
What is photosynthesis?
This zone is the largest environment on Earth and the organism that live here include sea pigs, basket stars, and sea spiders.
What is the Abyssopelagic zone?
Water acts as solvent, which means that substances can dissolve in water.
What is a universal solvent?
This trait of water causes sound to travel 4.5 times faster in water than in air?
What is higher density?
These ions come from volcanoes and hydrothermal vents.
What is sulfide and chloride?
Greater amounts of this element can cause greater mortality in marine larvae, suppress the immune system, reduce metabolic rates, alter internal chemical balance.
What is CO2 (carbon dioxide)?
In this layer, the only light is produced by bioluminescent (light - producing) animals, such as angler fish.
What is the Bathypelagic Zone?
The measure of the elastic tendency of liquids
What is surface tension?
As you go deeper, objects lose their true color and look blue. At about 1000m only darkness remains.
What is light penetration?
They are usually metals and metalloids, present in tiny amounts in the ocean.
What are Trace elements?
Because of this organisms with shells, skeletons and structures made out of calcium carbonate are at most risk since making shells requires energy in the acidic environment.
What is ocean acidification?
Sponges or sessile (non-moving) animals could also be found here.
What is Mesopelagic zone?
