Question 4

During a particularly cold winter in Florida,the temperatures remained below freezing for several weeks.To avoid freeze damage to the crops,farmers used well water to continuously spray the crops and maintain a protective coating of ice around the crops.Shortly after this long cold snap,sinkholes began forming throughout the region.Were these events linked?
