How does a rimstone dam form in calcite deposits?
Answer and explanation
Correct answer: By calcite deposition along the edges of shallow, flowing, lime-rich water
A rimstone dam is a small step or barrier built when calcite precipitates from thin, flowing films or shallow pools of carbonate-rich water, commonly in caves. The raised rim can slow water and encourage further deposition upstream. Option B is correct; desert deflation, river incision and sea-arch collapse are different processes and do not create this calcite feature.
