Question

1. scientists think that human activities that add carbon dioxide (co₂) to the atmosphere may be affecting the oceans through a process known as ocean acidification. when atmospheric co₂ 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 10¹² kg of carbon per year) and the amount of carbon stored in the atmospheric and ocean surface reservoir (in 10¹² kg of carbon). - based on the model, ocean acidification occurs because there is

Explanation:

Ocean acidification occurs as more carbon - dioxide from the atmosphere dissolves in ocean surface water, forming carbonic acid. The model shows an imbalance in carbon exchange between the atmosphere and ocean surface, with human - induced increase in atmospheric CO₂ contributing to this process.

Answer:

An increase in the amount of carbon dioxide moving from the atmosphere to the ocean surface.
