This report provides a detailed analysis of limestone, a sedimentary rock primarily composed of calcium carbonate. It delves into the rock's formation, describing how it originates in shallow, warm, and still marine environments from the accumulation of organic materials like shells and coral. The report outlines the processes involved in limestone formation, including both biological and chemical precipitation, as well as the role of evaporation. It includes a sedimentary rock forming process flow chart. The document discusses the minerals and elements present in limestone, its various structural forms, and how impurities can affect its color. The report also explores the applications of limestone, such as its use in construction, manufacturing, and agriculture. Finally, it highlights key learning outcomes from the exercise, including lab report writing skills, the sedimentary process, and the importance of limestone in society, with references to support the analysis.
