Answer
which of the following is an effect of fossil fuel emission on oceans?
a.
decreased ph
b.
decreased carbonate concentrations
c.
increased co2 absorption
d.
all of the above

Option (D).

Explanation:

The burning of fossil fuels emits large amount of carbon dioxide in the environment. The increase in the concentration of carbon dioxide also effects the life of ocean.

The pH level of ocean decreases due to the formation of H+ ions in the oceans as the carbon dioxide reacts with water and form carbonate ions. The carbonate concentration in the ocean decreases. The carbon dioxide is present in large amount and its absorption increases in the ocean.

Thus, the correct answer is Option D.
