What term is used to describe an underground area usually created when limestone is dissolved?

The term "cavern" specifically refers to a large underground chamber that is often formed through the natural dissolution of limestone by water, a process known as chemical weathering. This dissolution creates expansive spaces in the rock, resulting in a cavern that can be quite intricate, featuring stalactites and stalagmites. While "cave" is another term often used interchangeably with "cavern," it is generally a broader term that can apply to various formations. In contrast, a "tunnel" is typically a man-made structure and "mine" refers to a place where minerals or other geological materials are extracted. Therefore, "cavern" is the most accurate description for an underground area specifically created through the dissolution of limestone.
