Ocean Unit test part 1 Flashcards
(46 cards)
Mass, volume, and density are all measurement properties of…
matter
matter is…
anything that takes up space
what does density help with
helps us to classifying
objects and understand why they behave they way they do in nature
what is density
measure of how compact something is or more technical how much mass
per unit of volume
how do you measure density
D= m/v
where does the ocean salt come from?
weathering of rocks on the continents and Earth’s interior
salinity is?
measure of the total amount of salt dissolved in water
example of decrease in salinity
Precipitation, Runoff, Icebergs and Sea Ice Melting
example of increase in salinity
Evaporation, Formation of Icebergs and Sea Ice
The more salt in the water…
the denser it becomes
do dense things sink or float
sink
higher latitudes get less direct sunlight so generally cooler is from what?
Latitude
the deeper you go the colder it gets… to a point. This is from sunlight not reaching lower layers is the?
depth
thermocline is…
period of steep temperature drop
what is the largest reservoir of heat on Earth
the ocean
The colder water gets…
the denser it becomes until it freezes.
why does ice float
because the water expands when it freezes which causes it to be less dense
what are the 2 greatest factors that determine the density of oceanwater?
Salinity and temperature
what causes the ocean’s to drive out many processes?
Density differences
More salt =
more dense
colder water=
more dense
how does the ocean water hold gasses?
It stores oxygen and carbon dioxide. Many marine organisms rely on dissolved oxygen in order to live
which holds more oxygen, cold or warm water?
cold water
Aquatic plants, algae, and waves all add
oxygen back into the water
