premise: if granite is broken down into sediment sent2: formation in the rock cycle means an old class of rocks changes into a new class of rocks sent3: the sediment from the granite is buried and compacted sent4: the formation of sedimentary rock is a sequential process, with stages of weathering, erosion, deposition,burying, compaction sent5: if something is a stage in a process then that something is required for that process sent6: sedimentary rocks are formed by sediment / materials that settle compacting / cementing together sent7: in the formation of sedimentary rock , burying the sediments follows depositing the sediments.
hypothesis: a molecule of water is made of 2 hydrogen atoms and 1 oxygen atom
