Which of the following best explains why limestone areas are often dry?
Answer Details
Limestone areas are often dry because rainwater easily percolates through the porous limestone rocks. Limestone is a type of sedimentary rock that is formed from the accumulation of calcium carbonate shells and skeletons of marine organisms. This rock is highly porous and permeable, allowing water to easily flow through it. As a result, there is little surface water in limestone areas, and most of the water is stored underground in aquifers. This makes limestone areas prone to drought and often results in dry conditions. Therefore, the option that best explains why limestone areas are often dry is "Rain water percolates easily through limestone rocks".
