What happens to the limestone of Yucatan Peninsula when it rains?

When rain falls on the limestone of the Yucatan Peninsula, it seeps into the ground and reacts with the calcium carbonate in the limestone to form carbonic acid. This carbonic acid dissolves the limestone, creating a network of underground caves and sinkholes. These caves and sinkholes are a major tourist attraction in the Yucatan Peninsula, and they are also home to a variety of plants and animals.
