Unique Nature of Pure Water
What are marine organisms mostly made of
water
What fundamental properties are different underwater
Light, pressure, and sound
dead organisms floating down to bottom of ocean
Rising CO2 levels affect
The chemistry of the ocean
what is the top zone
Epipelagic zone
Matter consists of small units called
Atoms
What shines through the surface of the ocean
sunlight
The saltier the water
the denser it is
what percent of CO2 is emitted into the atmosphere each year in the ocean
30%
what zone is the twilight zone
Mesopelagic zone
62%
What weights are marine organisms holding up
Atmosphere and water
Variations to ocean salinity are the result of
addition or removal of pure water
Average pH of the ocean
8.0-8.3
What zone is the fourth one
abyssopelagic zone
What does temperature reflect
Average kinetic energy of the particles
As pressure increases gases are
compressed
what is salinity
total amount of salt dissolved in water
What does CO2 do to animals immune system
suppresses them
What zone contains trenches
Hadalpelagic zone
what substance naturally occurs in all three states of matter
water
Every 10m of depth is what added
another atmosphere of pressure
What is the percent of salinity in the ocean
35%
what ions are need by organisms to build and maintain shells
carbonate ions
Where are most sharks found
Epipelagic zone
