Limestone is formed primarily through ________.
A)direct precipitation from seawater
B)chemical interactions between ocean bottom sediments and ions in sea water
C)biochemical sediments secreted by marine organisms
D)evaporation of calcite rich seawater

Question

Quizplus · Accepted Answer

Limestone is primarily formed from biochemical sediments that are secreted by marine organisms, such as coral and mollusks. Over time, these sediments become compressed and cemented together to form solid rock. While other factors, such as chemical interactions and evaporation, can contribute to limestone formation, they are secondary processes.
