- Compaction is a kind of process
- Cementation is a kind of process
- Therefore, compaction and cememtation are kinds of processes

- Compaction and cememtation are kinds of processes
- Sedimentary rocks are formed by sediment compacting / cementing together
- Therefore, sedimentary rocks are formed by sediment going through the processes of compaction and cementation

Hence, sedimentary rocks are formed by sediment going through the processes of compaction and cementation
Question
Most sedimentary rock is made from sediments of other rock. Which of these processes would the sediments most likely go through to form sedimentary rock?
