How Are Shells Formed?
Shells are like beautiful, natural treasures from the sea. They start as little bits of sand or tiny creatures called mollusks. These mollusks have soft bodies and need protection.
So, they begin by making their own special homes, just like we build our houses. The mollusks use a magical material called calcium carbonate, which they take from the ocean. They use this material to create strong, hard shells around themselves.
As they grow, their shells also grow, and over time, they become those wonderful shells you find on the beach. Each shell is unique and can have different colors and patterns, just like our fingerprints.
So, when you see a seashell, remember it's a gift from the ocean, made by tiny creatures to keep themselves safe and sound in their underwater world.
