Why is surface drainage poorly developed in karst landscapes?
Answer and explanation
Correct answer: Water quickly enters the ground through cracks and solution-enlarged passages
Karst landscapes commonly develop on soluble limestone. Rainwater, often slightly acidic because it absorbs carbon dioxide, enlarges joints, bedding planes, and fractures by chemical solution. Much of the runoff therefore disappears underground and travels through caves, sinkholes, and conduits instead of forming a continuous surface drainage network. A correctly explains this process. The other choices describe impossible or unrelated mechanisms.
