Answer:
Emissions from power plants that burn fossil fuels increase atmospheric carbon dioxide, which is absorbed by the ocean.
Explanation:
Fossil fuels are burnt in power plants in order to produce energy. These fossil fuels contain carbon. Combustion of these fossil fuels emits oxides of carbon into the atmosphere. The oxides of carbon are carbon II oxide and carbon dioxide.
Carbon dioxide can be absorbed by the ocean to form carbonic acid according to the reaction equation;
CO2(aq) + H2O(l) ------> H2CO3(aq)
This is an anthropogenic activity which increases ocean acidification.
