Carbon dioxide (CO2) enters the ocean from the ______________________________.
atmosphere
photosynthesis of aquatic plants and algae
melting of sea ice
freezing of seawater
Density of seawater is affected by these two factors:
clarity and color
hydrogen ions and dissolved oxygen
transparency and turbidity
temperature and salinity
Ocean acidification occurs when too much _______________________________ enters the ocean from the atmosphere.
calcium carbonate
carbon dioxide
sulfur dioxide
nitrogen gas
Carbon dioxide diffuses into the ocean and combines with water (H2O) to form carbonic acid (H2CO3). This ultimately breaks down and releases _________________________ , causing the water to be more acidic.
sodium chloride
calcium carbonate
hydrogen ions
chlorophyll
Ocean temperature, salinity, dissolved gases, and density are the same in all parts of the ocean.
True
False
As a result of __________________________, there is not enough calcium carbonate available, needed by corals, crustaceans, mollusks (snails, etc).
chemosythesis
photosynthesis
ocean acidification
cellular respiration
