LowScientific, Technical, Academic
Definition
Meaning
A layer of Earth's atmosphere containing a high concentration of ozone molecules, located within the stratosphere.
The region of the stratosphere, approximately 10 to 50 km above Earth, where the ozone layer is found. This layer absorbs most of the Sun's ultraviolet radiation, protecting life on Earth. The term can sometimes be used to refer to the ozone layer itself.
Linguistics
Semantic Notes
Used almost exclusively in scientific contexts (meteorology, atmospheric science, environmental science). The term is largely synonymous with 'ozone layer' in practical usage, though 'ozonosphere' is the more formal, scientific designation of the atmospheric region.

Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'атмосфера' (atmosphere) in general. The specific translation is 'озоновый слой' or 'озоносфера'.
- Ensure the technical context is present; it's not a term for general air or sky.
Common Mistakes
- Misspelling as 'ozonosphere'.
- Using it interchangeably with 'atmosphere' (it is a specific part of the atmosphere).
- Incorrect pronunciation stressing the second syllable (e.g., /əʊˈzəʊnəsfɪə/).

FAQ
Frequently Asked Questions
Essentially, yes. 'Ozonosphere' is the more formal, scientific term for the atmospheric region containing the ozone layer.
It is highly technical. In everyday speech, 'ozone layer' is far more common and readily understood.
Its primary function is to absorb the majority of the Sun's biologically harmful ultraviolet (UV) radiation.
Because of the discovery of its depletion, particularly the 'ozone hole' over Antarctica, linked to human-made chlorofluorocarbons (CFCs).
