One Consequence of Global Warming Is the Melting of the Glaciers

question 28

Multiple Choice

One consequence of global warming is the melting of the glaciers and the resulting rise in sea levels. What will likely be the direct effect of this increase in sea levels on coral reefs?

• A) Productivity will increase as the pure water from the glaciers dilutes the nutrients in the sea.
• B) Coral reefs in shallow waters will grow more rapidly due to added protection against harmful UV radiation.
• C) Coral reefs will be stimulated to grow faster due to the dilution of the seawater's salt content.
• D) Productivity will decrease as nutrients trapped in the glacial ice are released and spread throughout the oceans by currents.
• E) Coral reefs in deeper waters will die because insufficient light reaches them for photosynthesis.
