Total questions: 20
Worksheet time: 15mins
What happens to 1/4 of the greenhouse gases in the atmosphere?
It is released into space.
It gets absorbed by the ocean.
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
In a more acidic ocean, the shells of organisms do not grow as easily.
