- ...Social stratification defines any structure of inequality that persists in a society across generations. Social strata are groups of people — who belong to the same social class or have the same social level. Social strata are organised in a vertical hierarchy.

- Stratified sampling. 'Strata' means 'layer'. A stratified sample is made up of different 'layers' of the population, for example, selecting samples from different age groups.The sample size for each layer is proportional to the size of the 'layer'.This is shown in the following equation:tratified sampling. 'Strata' means 'layer'. A stratified sample is made up of different 'layers' of the population, for example, selecting samples from different age groups.

- Lesson Summary. Rock strata are layers of sedimentary rocks and are found almost everywhere. The layering is the result of the rock-forming process. Studying sedimentary rock strata provides information about how the rocks formed, past tectonic activity and the relative ages of layers in a sequence.

What Is Critical Illness Insurance? Part of what makes these policies appealing is that they generally don’t cost a lot, especially when you get them through an employer. Some smaller plans run as little as $25 a month, which looks like a bargain compared to the cost of a typical, low-deductible health insurance policy.

- Principles of Stratigraphy Stratigraphy is the study of strata (sedimentary layers) in the Earth's crust. Geologist in the 1800s worked out 7 basic principles of stratigraphy that allowed them, and now us, to work out the relative ages of rocks.

clastic 1. (Geological Science) (of sedimentary rock, etc) composed of fragments of pre-existing rock that have been transported some distance from their points of origin. 2. (Biology) biology dividing into parts: a clastic cell. 3. (Medicine) able to be dismantled for study or observation: a clastic model of the brain.

Eat For Anabolism: Pre- And Post-Workout Nutrition For Muscle Growth Research supports the notion that there's a two-hour anabolic window following heavy resistance training.[1] Since a whole-food meal typically takes more time for preparation and even digestion, it's not your best choice in terms of an immediate post-workout meal, but it can be consumed an hour after your training.

Geology folding. Geological folding involves the plastic deformation (bending, buckling) of a single or multiple (stack) strata, such as sediments and rocks, which were originally planar horizontal surfaces.

- usage: The usual singular of this noun, taken from Latin, is stratum: the lowest stratum in society. The plural is strata: Several strata of settlement were discovered in the evacuation.

Fold (geology) Folding of rocks must balance the deformation of layers with the conservation of volume in a rock mass. This occurs by several mechanisms. The term fold is used in geology when one or a stack of originally flat and planar surfaces, such as sedimentary strata, are bent or curved as a result of permanent deformation. Synsedimentary folds are those due to slumping of sedimentary material before it is lithified.

respiration pseu·do·strat·i·fied ep·i·the·li·um. an epithelium that gives a superficial appearance of being stratified because the cell nuclei are at different levels, but in which all cells reach the basement membrane, hence it is classed as a simple epithelium. pseu·do·strat·i·fied ep·i·the·li·um.

- Stratification is the process of dividing members of the population into homogeneous subgroups before sampling. The strata should be mutually exclusive: every element in the population must be assigned to only one stratum. The strata should also be collectively exhaustive: no population element can be excluded.

Definitions &Translations In geography and geology, a cliff is a vertical, or near vertical, rock exposure. Cliffs are formed as erosion landforms due to the processes of erosion and weathering that produce them. Cliffs are common on coasts, in mountainous areas, escarpments and along rivers.

Stratified epithelium (Science: pathology) An epithelium composed of multiple layers of cells, only the basal layer being in contact with the basal lamina. The basal layer is of stem cells that divide to produce the cells of the upper layers, in skin, these become heavily keratinised before dying and being shed as squames. Stratified epithelia usually have a mechanical or protective role.
