Cast

Real World Example

Imagine you're baking a cake and you accidentally drop it, leaving a cake-shaped indentation in the flour on your counter. In a similar way, when an object like a shell or bone leaves an impression in sediment, minerals can seep in, filling the mold and eventually hardening to create a fossil cast. Just like how the spilled flour captured the shape of your cake, the minerals fill and preserve the details of the original object, creating a lasting replica long after the original has disappeared.
