Why are surface streams often fewer in karst regions?
Answer and explanation
Correct answer: Water enters joints and flows underground
The governing concept is underground drainage in permeable, soluble limestone. Rainwater enters joints, enlarged cracks, sinkholes, and solution channels instead of remaining in a surface channel. Consequently, streams may disappear underground and re-emerge at springs. Glaciers do not cover every karst region, sea waves affect coasts rather than inland drainage, and wind cannot transform water into sand. Therefore option A gives the causal explanation.
