(a) basic (b) acidic
100
Define Calcification
The process by which organisms creates calcium based structure, such as bone, coral, and mollusk shells
100
What contributes more CO2 to the environment: volcanos or people?
People!
200
pH levels in the ocean are...
decreasing
200
Name ocean life that are effected by ocean acidification (mentioned in presentation)
Mollusks, coral
200
Name two contributors to CO2 emissions
Deforestation and burning of fossil fuels
300
What percent of carbon ends up in the ocean?
30 to 40 %
300
Describe what happens to the metabolism of fish in more acidic oceans/how this changes the fish's actions.
Metabolic rate increases, fish must consume more
300
Define deforestation and two ways it contributes to ocean acidification
The clearing and burning of forests contribute to the amount of carbon dioxide globally, and with less trees to absorb carbon dioxide, there is more carbon dioxide in the atmosphere and oceans.
400
What compound is formed as a result of CO2 dissolving in the ocean that contributes to ocean acidification?
Carbonic Acid
400
Which compound necessary for calcification of mollusks and coral is significantly decreased because of ocean acidification?
carbonate
400
Worst car for environment:
Pick up truck
500
Describe (draw on the board!) the net reaction of CO2 dissolving in water and making the ocean more acidic
CO2 + H2O + CO3−2→ 2HCO3-
500
Explain or write the equation involved in decreased calcification
Ca2++CO32- ←→ CaCO3

How many pounds of CO2 dumped into atmosphere in specific year mentioned in presentation
38.2 billion
