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.
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.
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.
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.
seashells are made by rocks rubbing together
Seashells are made of animals body. Melded up and made a shell.
seashells are rocks. this would be because seashells are made out of minerals and formed by some of the same things as rocks. if you looked close enough at certain shells then you would see that seashells are alike with certain kinds and shapes of rocks.
Mostly calcium carbonate (limestone -chalk).
limestone is mostly seashells
Seashells are hard because they are mainly made of calcium, a hard mineral, which is what bones are made of.

Seashells are made of animals body. Melded up and made a shell.
Even the Sand Is Made of Seashells was created in 2006.
Seashells are not made out of only carbon. They are a mixture of compounds. Calcium carbonate is a main compound in them.
Magical Seashells.
limestone
no because they are not magnetic and their not made of magnet

Limestone is made up out of fossils of corals and shells from the water.

they are made mainly from calcium and from a few other minerals.
