Metamorphism of Rocks Process & Impact | What is Metamorphism? Raindrops (especially in dry environments) create splash erosion that moves tiny particles of soil. Larger particles will sink to the bottom early on in their journey because they are denser than the small particles that make their way to the end where the stream or river empties into a bigger body of water.

The molecules are pulled toward Earth by gravity. This includes dead leaves, decaying dead organisms, and other detritus from plants. In aquatic environments, water can form layers due to density, setting up a gradient of temperature called a thermocline. A third example of stratification occurs when soil forms from layers of sediment and organic matter. Cross stratification is commonly manifested as lamination, within a much thicker stratum, that is at least in some places at an angle to the bounding surface of the given thicker stratum.
