Yes, karst landscapes are found on every continent except Antarctica. Famous examples include the Guangxi region in China, the Burren in Ireland, and the Yucatán Peninsula in Mexico.
Karst aquifers can store vast quantities of groundwater but are extremely vulnerable to contamination due to rapid, unfiltered flow through solution channels.
It originates from the German name 'Karst', derived from the Slovene word 'Kras', which is the name of a limestone region in southwestern Slovenia and northeastern Italy.
