Swallow holes and disappearing streams are usually associated with
Answer Details
Swallow holes and disappearing streams are usually associated with limestone regions. This is because limestone is a soluble rock that can be easily eroded by weak acids, such as carbonic acid, which is found in rainwater. Over time, this erosion can create underground cavities and channels, which can cause the ground to collapse and form swallow holes. Disappearing streams can also occur in limestone regions when streams flow over porous limestone and then disappear underground through cracks and fissures.
