What is Host rock?

Host rock is the rock that surrounds something else, like a cozy blanket around a toy.

Imagine you have a chocolate bar inside a big cookie, the cookie is the host rock, and the chocolate is what's inside it. Just like how the cookie holds the chocolate in place, host rock holds things like minerals or crystals inside it.

Sometimes, something new grows inside the host rock. Think of it like a tree growing from a garden, the garden (the host rock) gives the tree (the mineral or crystal) space to grow and stay safe.

Host rock can be any kind of rock, like sandstone, limestone, or granite, depending on where you find it. It's like how your bedroom is your host room for your toys, books, and bed. The host rock is the home for all kinds of cool things hidden inside it!
