Unique Nature of Pure Water (Section 1)
Increases dramatically with ocean depth
what is pressure?
The average kinetic energy of the particles
What does temperature reflect?
The total amount of salt dissolved in water
What is salinity?
Organic compounds by photosynthesis
What is carbon dioxide converted into?
Hadalpelagic zone
What is known as the deepest place on earth?
Sound Fixing and Ranging Channel
What is SOFAR?
The ions in salt pulls apart or dissociate when the …….
What happens when salt dissolves in water?
Through river run off, groundwater seeps, the atmosphere, and human-derived inputs.
How do trace elements enter the ocean?
Rising CO2 levels
What affects the chemistry of the ocean?
The only light is produced by bioluminescent light
How do organisms in the bathypelagic zone see?
Ocean depth
what changes temperature, pressure, and density
The measure of the elastic tendency of liquids.
What is surface tension?
Temperature and salinity
What does the density of seawater depend on?
makes underwater sound go farther which affect whales and other animals that use sound.
What are one of the effects of ocean acidification?
Daily vertical migration
What is DVM?
6600-13100
What is the depth of the bathypelagic zone?
The sticking together of particles of the same substance
What is cohesion?
85% of the ions. This is why seawater tastes like table salt
What do sodium and chloride account for?
25%
about how much co2 enters oceans each year?
Epipelagic, mesopelagic, vathypelagic, abyssipelagic, and hadalpelagic
What are the 5 layers of the ocean?
Sound used for communication
What is sound propagation?
Chemical weathering of rocks on land and materials from Earth’s interior.
where do ions dissolved in seawater come from?
Trace elements are removed from the ocean when they are incorporated into sinking particles
What is “marine snow?
to build and maintain shells and other calcium carbonate structures.
why are carbonate ions needed by organisms?
Sharks, coral reefs, and seagrass beds
Which organisms are located in the Epipelagic zone?
