Relative age is important in areas that currently are or have been tectonically active in the past. How is stratification used in the study of variation? Stratified rock and water layers are caused by different factors. Quantitative terms applying to the thickness of stratification are very thick-bedded, thick-bedded, thin-bedded, very thin-bedded, laminated, and thinly laminated. Changes between strata are interpreted as the result of fluctuations in the intensity and persistence of the depositional agent, e.g., currents, wind, or waves, or in changes in the source of the sediment.

Their recognition and application are key to defining depositional . the hierarchical or vertical division of society according to rank, caste, or class: stratification of feudal society. Stratification in sedimentary rocks may result from changes in texture or composition during deposition; it also may result from pauses in deposition that allow the older deposits to undergo changes before additional sediments cover them. Create your account. Density differences can be caused by differences in temperature or, in the case of the ocean, differences in salinity. Plus, get practice tests, quizzes, and personalized coaching to help you When layers move because of plate tectonics or sliding faults, a scientist can compare the layers on either side of the line of movement and determine what direction the rocks moved and how far they moved. 3.
