Temperature
When will water generally become colder
The deeper you get
Why is overturning important
Overturning is important because when ocean plants die, they don’t recycle their nutrients; the plankton will be gone for hundreds, if not thousands of years
What is radiocarbon
a tool used to date organic materials like wood, animals, and clothing
Why is ocean water different than tap
because it is salt composed.
Name the four cycles covered
Water, Carbon, Nitrogen, and phosphorus
Where are warm waters found and why?
At surface levels because of the sun coming right down on it from above
What does overturning do
brings nutrients back up to the surface, which allows marine ecosystems to flourish and provide fish
The more radiocarbon, the __ the object
younger
How is salinity measured
Salinity is typically measured in terms of solute concentration
When does nitrogen come from and why is it important
A mmonia is made from bacteria in oceans, which change nitrogen gas into ammonia through ammonification, or NH₄+ (a chemical compound)Nitrates are a form of nitrogen that animals depend on for reproduction and life processes
What creates Radiocarbon
Extra protons acting together with neutrons
What are plankton important providers of
Plankton are important providers of oxygen, growing almost a ⅓ or so of the oxygen used in the ocean by marine life
Radiocarbon can be around for more than ___ years
5,000
What is the salt composition of salt water
35.5g
Describe the water cycle
Sun heats up water on the surface that evaporates, which then mixes with particles in the atmosphere (create condensation), and falls back into the ocean. Fog Drip is basically dew that falls. Sublimation is when solid ice goes straight into a form of gas known as water vapor, for example
What temperature does water freeze and boil?
32 degrees and 212 degrees Fahrenheit
Name three filter feeders
Clams, conchs and molluscs are also filter feeders – sifting plankton debris from the water for food, improving overall water quality in the reef.
True or False, are older waters and parts of the ocean utilizing oxygen more than newer waters are
True
What is the salt composition of other types of water
34.2g
Where does carbon dioxide come from
Carbon dioxide comes from weathering or volcanoes, makes its way into the ocean, and can be released into the atmosphere from respiration. Carbon dioxide can also be emissioned by cars and machines Carbon dioxide can also be found in soil,ground, and in chemical compounds. Trees also release carbon dioxide through transpiration or evapotranspiration (both mean essentially the same thing)
Because of the Greenland cod catch what is occurring
Amounts of overturning create drops in temperature as the fish are lost
What are harmful species
Harmful species are invasive species that can kill other species or make them die out
What do the first good herbivorous fish do
keep algae populations in check which often compete with corals for sunlight, nutrients and space.
Where does much rainfall occur, name two places
Along the equator; Amazon and Tripilanka
What is phosphorous used for, how is it formed, and who is it consumed by
Phosphorus is used for animal growth and reproduction. It is formed in volcanoes, aerosols, fertilizers,laundry detergent, and other human resources. It is consumed throughout the marine food web (an important source of food)Phosphorus can be recycled into ocean marine water
