Question

Scientists are monitoring the pH of oceans. Which of these are they most likely studying?
the population of polar bears
the rise of sea level
the level of carbon dioxide in the air
the health of coral colonies

Answer 1

Scientists monitoring the pH of oceans are most likely studying **the health of coral colonies**. Ocean pH levels are closely linked to ocean acidification, which affects marine life, particularly organisms that rely on calcium carbonate, such as coral reefs. Changes in pH can impact coral health, growth, and the overall biodiversity of the ecosystem. While the other options may be related to changes in ocean conditions, pH specifically connects to coral health and marine chemistry.
