Discuss the role of Sedimentary rocks in the rock cycle
What will be an ideal response?
Answer: When metamorphic, sedimentary and igneous rocks break down through weathering and erosion, they become either dissolved elements or fragments. The fragments are transported and deposited in sediment banks, which undergo lithification and become sedimentary rock again. The dissolved elements undergo precipitation, and are either deposited followed by lithification, or directly undergo lithification, again becoming sedimentary rock. Once sedimentary rock, it can be exposed to heat and pressure to become a metamorphic rock, only to start the cycle again.
