Coarse-grained sediment and poorly sorted rocks are usually found nearer to the source of sediment, while fine sediments are carried farther away. In a rapidly flowing mountain stream, you would expect to see boulders and pebbles. In a lake fed by the stream, there should be sand and silt deposits.

Classification - Clastic sedimentary particles and sedimentary rocks are classified in terms of grain size and shape, among other factors. In general, the coarser sediment gets left behind by the transportation process. Thus, coarse sediment is usually found closer to its source and fine grained sediment is found farther from the source.

sedimentary rock . The water molecule consists of two hydrogen atoms covalently bonded to one oxygen atom arranged in a specific and important geometry. The two hydrogen atoms are separated by an angle of about 105 degrees, and both are located to …

Rock types and structures allow the geologist to determine if the sediments were deposited by glaciers, rivers, lakes, deltas, beaches, sand dunes, wind, lagoons, continental shelf currents, reefs, or deeper ocean waters. High‐energy environments such as steep river channels usually deposit coarse arkosic sandstones or conglomerates.

2012/6/5 · Sedimentary texture encompasses three fundamental properties of sedimentary rocks: grain size, grain shape (form, roundness, and surface texture [microrelief] of grains), and fabric (grain packing and orientation). Grain size and shape are properties of individual grains. Fabric is a property of grain aggregates.
