Ozone Layer Speech Outline

Persuasive Speech Outline

General Purpose: To persuade

Specific Purpose: To persuade my audience that the ozone sand trap is non caused by human being and therefore requires no insurance against CFCs.

Central idea: The ozone layer/ localisation is caused by fluct. in the surroundings and CFCs are little if any of the cause of ozone depletion. CFCs are genuinely heavy, they stay close to the ground and do not touch on the stratosphere. Volcanos put turn up approx 10X more times chlorine than man produces. Ozone Center of WA states: The 1991 volcanic eruption of Mount Pinatubo light-emitting diode to temporary yucky ozone depletion but recent observations bind shown that ozone concentrations have returned to pre-Pinatubo levels. The change in the ozone layer is related to seasonal changes. (Cambridge University prof Dr. Glenn Carver)

Question of Fact

Organizational Pattern: Topical

Introduction: What is Ozone? Ozone is produced when highly energetic solar radiation strikes molecules of group O O2 this causes them to split and produce O molecules. They then join with the rest O2 and produce O3 molecules. These O3 molecules are what are known as Ozone. The mares nest in the ozone layer is not actually a hole it is a thinning of the ozone layer due to seasonal changes.

I. Staying low

a. The weight unit of CFCs makes it impossible for them to harm the stratosphere. Here are a fewer examples; air 29, nitrogen 32, CFCs over 100, Hydrogen 2, O2 16.

b. Volcanos spew 289 zillion scores of HCL (also an ozone depleting substance, this seems more likely to cause harm to the Ozone Layer. As it is an upward motion of the eruption.

II.Natural Causes

a.Volcanos again: 289 billion tons of HCL compared with 750,000 tons of manmade HCL.

b.



It was once thought that the methane gas from the flatulence of cows was the...

CFCs are very heavy, they stay close to the ground and do not affect the stratosphere. That is a little bit strange...Volcanos put out approx 10X more times chlorine than man produces. Ozone Center of WA states: The 1991 volcanic eruption of Mount Pinatubo led to temporary severe ozone depletion but recent observations have shown that ozone concentrations have returned to pre-Pinatubo levels. The change in the ozone layer is related to seasonal changes. (Cambridge University Professor Dr. Glenn Carver)I think this was a very good example!
