Which molecule makes water acidic?
Carbonate Ions
Carbon Dioxide
What happens to 1/4 of the greenhouse gases in the atmosphere?
It is released into space.
It gets absorbed by the ocean.
When carbon dioxide ions react with water, what molecules do they release?
Hydrogen Ions
Carbonate Ions
According to this slide
CO2 is causing marine life to die by "poisoning' the water
CO2 is destroying sea shells
CO2 is formed from the combustion of Octane
This image demonstrates that
There is a direct correlation with the atmospheric CO2 and the CO2 in seawater
That pH of the ocean increases as the atmospheric CO2 increases
That there is no correlation between pH of the ocean and atmospheric CO2
What do some marine creatures do with the carbonate ion?
use it as a food source
use it as a defense mechanism
use it to build shells and exoskeletons
use it to cool body temperatures
Ocean acidification makes it more difficult for marine organisms to hear each other, and predators.
True
False
In a more acidic ocean, the shells of organisms do not grow as easily.
True
False
Ocean acidification raises the pH of the ocean .
True
False

H2CO3
CO3-
CO2
Which organism might benefit from the increase of carbon dioxide in the world’s oceans?
crabs and lobster
Fishes
Clams and oysters
Sea grasses
All carbon dioxide gas found in the ocean is there because humans are causing pollution from burning fossil fuels.
True
False
CO2 + H20 -->
H2CO3
CO3
CO2
H3O+
