GENERAL GEOLOGY

Detailed explanation-1: -In geology and related fields, a stratum (PL: strata) is a layer of rock or sediment characterized by certain lithologic properties or attributes that distinguish it from adjacent layers from which it is separated by visible surfaces known as either bedding surfaces or bedding planes.

Detailed explanation-2: -Stratigraphy is a branch of Geology and the Earth Sciences that deals with the arrangement and succession of strata, or layers, as well as the origin, composition and distribution of these geological strata.

Detailed explanation-3: -stratum, plural Strata, sedimentary rock layer bounded by two stratification planes, the latter being produced by visible changes in the grain size, texture, or other diagnostic features of the rocks above and below the plane.

Detailed explanation-4: -Rock strata and the subfield of stratigraphy are important because they enable scientists to understand how and when sediments were likely deposited to form the layer. Scientists can then extrapolate and understand the geological history of the area, along with the tectonic and climate activity of that time period.

Detailed explanation-5: -Stratigraphists examine layers in rocks or soil to figure out how that area of land came to be and the accurate sequence that occurred. Stratigraphy is a scientific discipline concerned with the description of rock successions and their interpretation in terms of a general time scale.
