What is geoscience?
Geoscience (also called Earth Science) is the study of Earth. Geoscience includes so much more than rocks and volcanoes, it studies the processes that form and shape Earth's surface, the natural resources we use, and how water and ecosystems are interconnected. Geoscience uses tools and techniques from other science fields as well, such as chemistry, physics, biology, and math! Read more...

Interesting ... what's special about that one spot on earth that all 4 of the deepest caves would form there?
Anyway, I imagine this graphic is likely to change in the future, since the deepest parts of caves are often the least well-explored. When I was doing work as a cave explorer, we often did day trips to map parts of the upper cave, but trying to get to the deepest portions involved major multi-day expeditions. To get to the deepest unexplored frontier of one cave I worked in required a 4-day journey, one way.
there's a note in the middle
Pretty much all caves are in karst topography. What's so special about this area in particular?
IIRC it's because the caves start high up in the mountains and are mostly above sea level. Caves that start closer to sea level can't be as deep, something about the water table. Or at least, we can't explore caves as easily when they're full of water. I think those caves in Georgia are mapped up to where the water table is and are theorized to be even deeper
