Concept:Limestone is permeable, so rainwater drains underground instead of staying on the surface.
Explanation:Limestone rocks contain joints, cracks, and bedding planes.
Rainwater easily seeps into these openings and percolates downward.
Over time, the openings are enlarged by solution, which increases permeability.
As a result, surface water is scarce and streams are often absent.
This is why limestone areas appear dry on the surface.
Answer:C. Rain water percolates easily through limestone rocks
