Webatmos phere (troposphere), ozone is formed by a different set of chemical reactions that involve naturally occurring gases and those from pollution sources. Q2 How is ozone formed in the atmosphere? Figure Q2-1. Stratospheric ozone production. Ozone is naturally produced in the stratosphere by a two-step reactive process. WebAntarctic is known as the “ozone hole” (see Q11). The ozone hole appears over Antarctica because meteorological and chemical conditions unique to this region increase the effectiveness of ozone destruction by reactive halogen gases (see Q8).

WebThe Earth's atmosphere is continuously stirred over the globe by winds. As a result, ozone-depleting gases get mixed throughout the atmosphere, including Antarctica, regardless of where they are emitted. The special meteorological conditions in Antarctica cause these gases to be more effective there in depleting ozone compared to anywhere else. Web9 apr. 2007 · Ross J.

Web10 jul. 2012 · As the temperatures begin to warm up, fewer stratospheric clouds form, and so the creation of ozone-destroying forms of chlorine slows. The ozone loss bottoms out for the season, and the ozone layer gradually regenerates over the summer. (Ozone naturally forms when oxygen is exposed to ultraviolet radiation from the Sun.) WebOzone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NO X ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons. This reaction can occur both near the ground and high in the atmosphere. Just remember that ozone is "Good Up High, Bad Nearby." Stratospheric ozone is good …
