Read about how these rocks form through compaction and lithification, and how weathering and erosion destroy them. The text supports the KS2 and KS3 science curriculum, covering topics such as the many kinds of sedimentary rock, rock identification, and fossils. The text also explores how people use sedimentary rocks, and where on Earth the most beautiful examples are found. Stunning photographs, sidebars, and fact boxes further enhance the learning experience.
