Pronunciation: [stɹˈatəsfˌi͡əz] (IPA) 
The word "stratospheres" is spelled with a long "o" sound (notated as /oʊ/) in the second syllable, making it distinct from the word "stratosphere" with a short "o" sound (/ɑ/). The IPA phonetic transcription for "stratospheres" is /ˈstrætəsˌfɪərz/, with stress on the first and fourth syllables. The plural form of "stratosphere," it refers to multiple layers of the Earth's atmosphere between the troposphere and mesosphere.
Stratospheres is a plural noun that refers to the uppermost layer of the Earth's atmosphere, located above the troposphere and below the mesosphere. It is characterized by its relatively stable, dry, and thin nature.
The stratosphere extends from approximately 10 kilometers (6.2 miles) above the Earth's surface to around 50 kilometers (31 miles) high. One of its most notable features is the presence of the ozone layer, a region rich in ozone molecules that absorbs a significant portion of the Sun's ultraviolet radiation. This absorption shields the Earth's surface from harmful UV rays and plays a crucial role in protecting life on our planet.
Within the stratosphere, temperatures increase with altitude due to the absorption of ultraviolet radiation by the ozone layer. This temperature profile creates a stable atmospheric condition, wherein vertical mixing is limited, resulting in clear skies and smooth air currents. Consequently, the stratosphere is an ideal medium for long-distance flights and high-altitude piloted and unmanned aircraft.
The term "stratospheres" can also be used more broadly to refer to similar regions found in other planets or celestial bodies with an atmosphere. For example, the gas giants in our solar system like Jupiter and Saturn possess their own stratospheres, although their compositions and characteristics may differ from Earth's stratosphere.
In summary, stratospheres are the upper layers of the Earth's atmosphere characterized by their stable, dry, and thin nature, extending from approximately 10 to 50 kilometers above the Earth's surface.
The word "stratospheres" is a derivative of the word "stratosphere".
The term "stratosphere" is a combination of two Greek words: "stratos" meaning "layer" or "spread out", and "sphaira" which means "sphere" or "ball".
The stratosphere is a layer of the Earth's atmosphere that lies above the troposphere and below the mesosphere. The word was first coined in the early 20th century, around 1908, by the French meteorologist Léon-Philippe Teisserenc de Bort, who is credited with its discovery. Since then, the term has been widely used in the field of atmospheric sciences and has also been adopted into general vocabulary.
The plural form "stratospheres" simply adds an "s" to the singular form, following the established rules of English pluralization.
