Question 1 Scientists think that human activities that add carbon dioxide (CO,) to the atmosphere may be affecting the oceans through a process known as ocean acidification. When atmospheric CO, dissolves in the water of the ocean surface, carbonic acid could be produced. The model represents part of the global carbon cycle. The model shows the cycling of carbon between the atmosphere and the ocean surface (in 10\" Kg of carbon per year) and the amount of carbon stored in the atmospheric and ocean surface reservoirs (in 10" kg of carbon). Part of the Carbon Cycle Atmosphere (600) Ocean surface (1,000) Based on the model, ocean acidification occurs because there is more CO leaving the ocean than entering the ocean
