Web2. The grain size of the sedimentary rock tells you about the energy of the environment. Water must move fast to carry pebbles and cobbles (see “grain size” column in the Scheme for Sedimentary Rock Identification). Therefore, a conglomerate must have been deposited (or dropped) quickly from fast moving water. Slower flowing water can deposit sand.
