That's correct! Karst topography is a landscape characterized by sinkholes, caves, and underground drainage systems. It develops in regions where soluble rocks, primarily limestone, dolomite, or gypsum, are present.

Here's how it works:

* Dissolution: Rainwater, slightly acidic due to dissolved carbon dioxide, reacts with the soluble rocks, dissolving them over time.

* Underground Drainage: The dissolved rock creates underground channels and caves.

* Sinkholes: When the underground cavities become large enough, the overlying rock may collapse, forming sinkholes.

Karst landscapes are found worldwide and can be quite dramatic, featuring:

* Caves: Large, underground chambers often with intricate formations like stalactites and stalagmites.

* Springs: Where groundwater emerges from the underground system.

* Disappearing Streams: Streams that suddenly vanish into the ground through sinkholes.

So, if you're in an area with a lot of sinkholes, chances are you're in a karst region!
