Typical environments include hot springs, lakes and coral reefs in the tropical oceans. However, the most dominant depositional environment of limestone is shallow waters of tropical seas, where carbonate-shelled plants and animals proliferate.The lichens may possess acidic properties which dissolves the limestone and indirectly enhances chemical and physical weathering. Large tree roots growing in the area can also exert pressure on limestone. The combination of all 3 weathering processes subsequently disintegrates the limestone, and soil genesis begins. The process of limestone formation typically occurs in shallow, warm, marine environments where the accumulation and compaction of sedimentary materials takes place over long periods of time. Limestone can also form from the evaporation of water in caves and other confined spaces.
