Within any given depositional environment, various physical and biological processes act to transport and deposit sediment. These processes result in various distributions of grain size and sedimentary structures that characterize the deposited sediment. Relating these features back to the processes that produced them is the basic method used by geologists to interpret the depositional environment of sedimentary sequences (Figure 1).
