How are seashells made?

Answer 1

Almost all of a mollusk shell is composed of calcium carbonate. It may take a few different forms and thereby appear differently, but CaCO3 is the main material in the shell. Need links? You got 'em.

Answer 2

Seashells are created by snails. When snails are first born, their skins are soft, then they harden and calcify and detach from the rest of the body. They continuously grow around their own shells more and more, which is where the spiral comes from. When the snails die, the soft portion decays and the hard shell remains.

Some shells are also those of clams, scallops, or oysters. Depending on the location, any of these might be more numerous than the shells of snails. In any case, the process of formation is similar: A soft-bodied mollusk secretes calcium carbonate which accumulates as the shell as the animal grows, then the empty shell remains when the animal dies.

Answer 3

S eashells are formed when a mollusk formed a soft shell while in the larva form. it eventully hardens. When you see seashells with layers curled, that is its years. The old it is, the bigger the seashell.

Answer 4

Seashells get their shapes naturally. The animals that live in the seashells are the ones that make the designs and shapes o f the shell.

Answer 5

seashells are made by rocks rubbing together
