Ozone molecules - PowerPoint PPT Presentation
T he Ozone Hole
T he Ozone Hole. Ange Darnell. Ozone. Ozone is a relatively unstable molecule made up of three oxygen atoms. The majority of this compound exists in the stratosphere (15 miles up) and shields the Earth from harmful UV radiation from the sun. Source: University of Alaska.

Ozone Depletion
Ozone Depletion. O 3. Ozone Factoids. Good in the stratosphere, bad in the troposphere Produced at a height of ~50 km, settles to a height of 23 km Filters out 95 – 99% of incoming UV-A and UV-B ( 0.2 m - 0.3 m ; m = 10 -6 m )

WHAT IS OZONE DEPLETION?
WHAT IS OZONE DEPLETION?. WHAT IS OZONE?. Triatomic form of oxygen (O 3 ) Strong oxidant (chemically reactive) In lower atmosphere = pollutant In stratosphere = protective “shield” • 90% of O 3 found b/w 15-40 km altitude • 99% of UV radiation screened by ozone

The Ozone Shield
Section 13-2. The Ozone Shield. Ozone Layer. Area in the stratosphere where ozone is highly concentrated Ozone: 3 atoms of oxygen (O3) Absorbs most of the harmful ultraviolet (UV) radiation from the sun Acts like a sunscreen for the Earth. Chemicals That Cause Ozone Depletion.

CFCs and Ozone
CFCs and Ozone. By Peter Sawyer. CFCs Breakdown. CFCs are Halogenoalkanes They contain only Chlorine, fluorine and carbon! All the hydrogen's have been replaced. CFCs Breakdown. Very stable due to the CARBON-HALOGEN bonds. CFCs properties . VERY stable Volatile Non-flammable Non-toxic

Ozone depletion
Ozone depletion. Ozone layer is a concentration of ozone molecules in the stratosphere (10-50km above earth’s surface) Stratospheric ozone shields earth from sun’s ultraviolet (UV) rays, reducing radiation

Chapter 16 Section 1 Earth’s Atmosphere
Chapter 16 Section 1 Earth’s Atmosphere. * a thin layer of air that forms a protective covering around the planet . 1. Earth’s atmosphere. * keeps days cool and nights warm * protects life-forms from some of the Sun’s harmful rays. * start = Earth’s surface * end = outer space.
