weathering is a kind of erosion & erosion causes deposition ->  weathering causes deposition  weathering causes deposition & the formation of sedimentary rock is a sequential process, with stages of weathering, erosion, deposition,burying, compaction ->  a stage in the formation of sedimentary rock is rock being weathered and then deposited  weathering is a kind of geologic process & deposition is a kind of natural process ->  weathering and deposition are kinds of processes  a stage in the formation of sedimentary rock is rock being weathered and then deposited & weathering and deposition are kinds of processes ->  a process in the formation of sedimentary rock is rock being weathered and then deposited  a process in the formation of sedimentary rock is rock being weathered and then deposited & weathering / mechanical weathering means breaking down rocks / surface materials from a larger whole into smaller pieces by weather / mechanical means ->  a process in the formation of sedimentary rock is rock being broken down and then deposited  sedimentary rocks are formed in layers & sedimentary rocks are formed by deposition ->  sedimentary rocks are deposited in layers  a process in the formation of sedimentary rock is rock being broken down and then deposited & sedimentary rocks are deposited in layers -> a process in the formation of sedimentary rock is rock being broken down and then deposited in layers
