What is a large hollow space made underground in limestone by groundwater?
Answer and explanation
Correct answer: Cave
The governing concept is groundwater solution in limestone, a major process of karst development. Slightly acidic groundwater enters joints and bedding planes and dissolves the rock over long periods, enlarging underground passages into a large hollow space called a cave. A barchan is a crescent-shaped wind dune, an esker is a ridge deposited by meltwater beneath ice, and an alluvial fan forms where a stream leaves a mountain valley. Hence option C is correct.
