How Limestone is Formed, Where Does it Form?
Limestone, a sedimentary rock composed primarily of calcium carbonate (CaCO₃), forms via two predominant pathways: biogenic precipitation and abiogenic precipitation. Understanding these processes necessitates an examination of the relevant chemistry, geological forces, and temporal scales involved.
The Rock Cycle
The rock cycle is an ongoing process that converts one type of rock into another. The rock cycle is the natural, continuous process that forms, breaks down, and reforms rock through geological, chemical, and physical processes. Through the cycle, rocks convert between igneous, metamorphic, and sedimentary forms. ... Limestone …
