Question

24: esatu4: interactionsbetweenearthssystems about the impact of environmental stressors like ocean temperature and acidification? (1 point) these stressors improve reef growth these stressors increase the mineral content of seawater these stressors have no effect on reef structure these stressors reduce reef growth and increase erosion risk which of the following would most likely occur if coral reefs continue to weaken over time? (1 point) greater protection of inland ecosystems more severe erosion

Explanation:

1. For the first question: Ocean warming causes coral bleaching (corals expel symbiotic algae they need for energy and growth), and ocean acidification reduces the availability of carbonate ions that corals use to build their calcium carbonate skeletons. Both stressors hinder reef growth and make existing reef structures more vulnerable to erosion.
2. For the second visible question: Coral reefs act as natural barriers that absorb wave energy, protecting coastlines from erosion. If reefs weaken, they can no longer buffer coastlines, leading to more severe coastal erosion.

Answer:

1. These stressors reduce reef growth and increase erosion risk
2. More severe erosion
