STRATIFIED ROCKS. No direct relationship exists between the thickness and extent of strata and the rate of deposition or the time represented; for example, a stratum of limestone 2.5 cm (1 inch) thick may take longer to form than a stratum of sandstone 3 m (10 feet) in thickness. However, the sun's rays can only warm so much water, so at some point the warm comfortable water will quickly turn cold. Fragmental volcanic material becomes sorted in flight under the influence of gravity, particle size, and wind. 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.
