Question

Quizplus · Accepted Answer

Cavern openings to the surface are usually small, as they are formed by the gradual dissolution of limestone or other soluble rocks by acidic groundwater. These openings can range in size from narrow cracks to larger cave entrances, but they are typically not the largest part of the cavern. Hot springs may be found in or near caverns but are not necessarily associated with cave openings, and the warmth of the opening will depend on factors such as sunlight exposure and air circulation. Triangular shapes are not a common feature of cavern openings.
