Travertine

Travertine is a type of rock that is formed from limestone. When water flows through limestone for a long time, it dissolves some of the minerals in the rock and carries them away. Then, when the water reaches the surface and evaporates, the minerals are left behind and form a hard, thick deposit called travertine.

Travertine is often used as a building material because it's strong and durable, but also looks really pretty. It can come in many different colors, such as white, beige, gray, and even pink, and has a kind of bumpy or textured appearance. This makes it really nice for things like countertops, floors, and walls, as it adds a unique touch of nature to a room.

In fact, you might have even seen travertine without realizing it – it's often used in fancy buildings and homes, or sometimes in outdoor spaces like pools and patios. But even though it looks nice and is strong, it's still important to take care of it – because travertine is formed from limestone, it can react to things like acidic foods or cleaning materials and become damaged.

So, to sum it up – travertine is a kind of rock that's formed from limestone and water, looks bumpy or textured, and is often used in buildings or outdoor spaces to add a natural touch. Just make sure to take good care of it!
