Question
17. Scientists have observed that shells of some marine animals have thinner shells than several decades ago. How could this trend be related to increased greenhouse gasses?(1 point)
Responses
Fossil fuel spills in the ocean prevent marine animals from building shells.
Fossil fuel spills in the ocean prevent marine animals from building shells.
Higher carbon levels mean the marine animals have less materials to build shells.
Higher carbon levels mean the marine animals have less materials to build shells.
Atmospheric greenhouse gasses eventually circulate to the oceans making the water more acidic and this makes it harder for animals to build shells.

The correct response is:
**Atmospheric greenhouse gasses eventually circulate to the oceans making the water more acidic and this makes it harder for animals to build shells.**
This increase in ocean acidity, caused by higher levels of carbon dioxide in the atmosphere, impacts the availability of carbonate ions, which are essential for marine animals to build their calcium carbonate shells, resulting in thinner shells over time.
