Stratification means to categorize something or something that has been ordered. Stratification is a system or formation of layers, classes, or categories. Stratification is used to describe a particular way of arranging seeds during planting, as well as the geological layers of rocks.
How does stratification occur?
Stratification is created by a Density difference between two layers of water and can arise as a result of differences in salinity, temperature, or a combination of both. Stratification is more likely when the mixing forces of wind and swell are minimal, and this occurs more frequently in the summer months.
Additionally, what is a stratification map? Stratification Techniques
When you plot or graph the collected data on a scatterplot, rule chart, histogram, or other analysis tool, you use different markers or colors to distinguish data from different sources. Data differentiated in this way is called “stratified“.
And what is another word for stratification?
Synonyms. laminar leafy superimposed laminar leafy stratified leafy leafy.
Why is stratification necessary?
Seed stratification is the process of disrupting seed dormancy to encourage this germination. For seed stratification to be successful, it is necessary to mimic the exact conditions they need when they emerge from dormancy in nature.
What is density stratification?
Stratification of substances by density; highest density below, lowest density above. Density stratification explains the composition of the Earth because the core is densest and the Earth is stratified up to the atmosphere with layers of lower and lower density.
What is the difference between scarification and stratification?
Stratification and scarifying in nature. Animals can also scarify seeds by eating and digesting the hard seeds. This process is commonly referred to as stratification or cold stratification. Some seeds are not hardy enough for cold winter temperatures, but many perennials are grown this way.
What is risk stratification?
Risk stratification is a tool for identifying – and predicting – which patients are at high risk – or are likely to be at high risk – and prioritizing treatment of their care to prevent worse outcomes – in this case, amputation, blindness, or death.
What causes water stratification?
The heating of the water surface by the sun causes fluctuations in water density and triggers thermal stratification. Cooler, denser water settles to the bottom of the lake, forming the hypolimnion. A layer of warmer water called the epilimnion floats on top.
What is highly stratified?
Adjective. A stratified society is a society divided into different classes or social strata. [formally] a highly stratified, unequal and class-divided society. You may also like.
When can stratification be used?
Clinical trial stratification is the subdivision of subjects and outcomes by a factor other than the given treatment. Stratification can be used to ensure equal assignment of subsets of participants to each experimental condition. This can be by gender, age, or other demographic factors.
What is a synonym for hierarchical?
Synonyms. gradable stratified class-conscious vertically hierarchically hierarchically graded ranked. Antonyms. not hierarchical not stratified not upright sloping.
What is HVAC stratification?
Stratification is the formation of different temperatures in specific areas of your home. Air conditioning and heating systems that do not work often lead to stratification and thus to uncomfortable temperatures. When your air conditioner is running, the cold air falls down, displacing the warmer air.
What does it mean to stratify a population?
Stratified sampling refers to a type of sampling method . In stratified sampling, the researcher divides the population into separate groups called strata. A probability sample (often a simple random sample) is then drawn from each group. Or it is possible to increase the accuracy with the same sample size.
How to use social stratification in a sentence?

What are the four principles of social stratification?
Concrete forms of social stratification are diverse and numerous. However, sociologists have grouped most of these into four basic systems of stratification: slavery, estate, caste, and class.
Do all seeds need stratification?
Many plants require cold seed stratification around the dormant cycle to break through and germinate. Below are some common plants that need cold seed treatment (Note: This is not an exhaustive list. Make sure you research the germination needs of your particular plants beforehand): Butterfly bush.
How does cold stratification work ?
Cold stratification is the process of exposing seeds to both cold and humid conditions. Seeds of many trees, shrubs, and perennials require these conditions before germination can occur.
Why is water stratification important?
Water stratification also creates barriers to nutrient mixing between layers. If nutrients from the benthos cannot reach the photic zone, the phytoplankton may be limited by nutrient availability. Lower primary production also leads to lower net productivity in water bodies.
What are examples of social stratification?

- Wealth and income – This is the most common basis of stratification.
