Karst Landscapes Hide Caves, Springs, and Sinks

喀斯特地貌隐藏洞穴、泉眼与落水洞

  1. Karst forms when rainwater slowly dissolves limestone bedrock.
  2. Underground rivers carve caves and leave behind tall stone pillars.
  3. Sinkholes appear where surface rock collapses into empty spaces below.
  4. Springs flow where underground water meets the land surface naturally.
  5. Many karst areas have few surface rivers but rich groundwater supplies.
  6. Farmers in karst zones must watch for sudden ground collapse risks.
  7. Bats and rare cave insects live only in dark, humid karst environments.
  8. Limestone cliffs above caves show layers of ancient sea life fossils.
