chapter 1
The rock cycle describes the continuous process of formation, alteration, and transformation of rocks on Earth's surface. It involves the interplay of igneous, sedimentary, and metamorphic rocks through various geological processes like weathering, erosion, deposition, heat, and pressure.
Sedimentary rocks are formed from deposits of pre-existing rocks or pieces of once-living organism that accumulate on the Earth's surface. If sediment is buried deeply, it becomes compacted and cemented, forming sedimentary rock.
chapter 2
Getting a sedimentary rock involves transforming sediment into rock through diagenesis processes. Diagenesis is all the physical and chemical changes a sediment undergoes after deposition in a sedimentary basin under relatively low pressure and temperature conditions that prevail at shallow depths. Diagenesis stops where metamorphism begins.
