Question

__ 19. What is the significance of the animation showing changes in ocean acidity from 1765 to 2100? A) It illustrates the historical stability of ocean chemistry. B) It highlights the rapid increase in ocean acidity due to human activities. C) It shows that ocean acidity is decreasing over time. D) It emphasizes the importance of marine tourism.

Answer 1

The correct answer is B) It highlights the rapid increase in ocean acidity due to human activities.The animation showing changes in ocean acidity from 1765 to 2100 is significant because it highlights the rapid increase in ocean acidity due to human activities. This is a major environmental concern as the absorption of excess carbon dioxide (CO2) from the atmosphere leads to the formation of carbonic acid, which lowers the pH of the ocean and increases its acidity. This can have detrimental effects on marine ecosystems, including the ability of organisms such as corals and shellfish to build their shells and skeletons.
