Acid, particularly in the form of increased carbon dioxide in the ocean leading to ocean acidification, negatively impacts the shells of sea creatures like mollusks and coral. The lowered pH levels reduce the availability of carbonate ions, which are essential for shell formation. This can result in thinner, weaker shells, making these organisms more vulnerable to predation and environmental stress. Overall, acidification poses a significant threat to marine ecosystems that rely on calcifying organisms.

Mother-of-Pearl is found in Oyster shells
From the shells and skeletons of dead sea creatures.
chalk is produced by the shells of sea creatures lying on the sea bed and then the pressure of the water pushing the shells together until they form stone
they were made when tiny sea creatures shells were compacted and cemented on the sea floor
Sea creatures with shells have evolved various adaptations to protect themselves from predators in their marine environment. These adaptations include hard shells that provide physical protection, camouflage to blend in with their surroundings, and the ability to retreat into their shells when threatened. Some species also have spines or other deterrents to ward off potential predators. Overall, these adaptations help sea creatures with shells survive and thrive in their underwater habitats.

Yes, sea shells are made mostly of calcium carbonate, which will react with hydrochloride acid to produce water, carbon dioxide, and calcium chloride. CaCO3 + 2HCl --> H2O + CO2 + CaCl2
firstly they fizz. after 3 days a paste forms on top of the shell parts that are out of the vinegar, and around the liquid level of the bowl. we removed the shells from the vinegar and compared them with untouched shells. the vinegar shells were crumbly. we could break them with our hands, compared to the untouched shells which were still hard and shattered when dropped on the ground.
