EASY QUESTION!! PLEASE HELP ME! Which of these surface features are formed when the acid in groundwater reacts with limestone? a.rivers and springs b.sinkholes and caves c.hotsprings and geysers d.wetlands and volcanoes

OpenStudy (anonymous):

I would think its b. Since limestone (CaCO3) would react with the acid to form CaOH and some other acid. Eventually the limestone will get dissolved forming caves etc which called Karsts. http://en.wikipedia.org/wiki/Karst
