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
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 happens to water when it is dissolved with carbon dioxide?
it becomes more acidic
it becomes more basic
it becomes healthier to drink
it turns into coal
