What is the origin of all the lakes and springs in western Florida? * limestone caverns and sinkholes filled with water because of the high water table. Chapter 9 - Multiple choice questions: What causes sinkhole collapse; where is the cavity that it collapses into and how does that cavity form? A limestone cavern dissolves out with acid rain; a sinkhole forms when its roof collapses. * Soil above a limestone cavern percolates down into the cavern, leaving a soil cavity above; that cavity may collapse to form a sinkhole. An underground erodes a wide area; a sinkhole forms if its roof collapses The roof of a gold or copper mine collapses to form a sinkhole. Families of moles or gophers dig large underground chambers that can collapse to form sinkholes. What causes caverns in limestone? Hard grains of quartz sand carried in underground streams erode the soft limestone. They form when above collapse into the limestone Limestone readily dissolves in seawater so the caverns formed originally at sea level Groundwater in limestone is somewhat caustic so over many years it dissolves limestone.. * Rainwater dissolves carbon dioxide to make weak carbonic acid that dissolves limestone. Where in the North America are sinkholes most prevalent and why? In Michigan because outcrops of limestone are widespread and it is surrounded by the Great Lakes. In Washington State because of all the rain west of the Cascades In metamorphic rocks of the Canadian Shield because of all the lakes * In Florida because it is almost all limestone and has abundant groundwater In Colorado because layers of sedimentary rocks under the Great Plains bend up to the surface there.. What is karst and how does it form? * Karst is the ragged surface dissolved on the surface of limestone bedrock formerly buried under soil. Karst is windblown dust deposited in areas of dune-like hills. Karst is the deposit of calcium carbonate that precipitates on rocks in soil when groundwater evaporates. Karst is the cold wind that blows off the North Atlantic Ocean at times in late Fall.
