What Are Some Questions About The Ozone Layer? Ozone Depletion. When chlorine and bromine atoms come into contact with ozone in the stratosphere, they destroy ozone molecules. One chlorine atom can destroy over 100,000 ozone molecules before it is removed from the stratosphere. Ozone can be destroyed more quickly than it is naturally created. What
What Are 3 Causes Of Depletion To The Ozone Layer? Chlorofluorocarbons What are the main causes and effects of ozone layer depletion? Ozone depletion is primarily caused by human activities. The main effect of ozone depletion is an increase in UV-B rays reaching the earth’s surface. … CFCs and halons break down into chlorine and
What Characteristics Of CFC And HCFC Make Them More Likely To Reach The Stratosphere? What characteristics of CFCs make them more likely than most other chlorine compounds to reach the stratosphere? CFCs neither dissolve in water nor break down into compounds that dissolve in water, so they do not rain out of the atmosphere. What
What Do CFCs Do To Our Atmosphere? Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth’s protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate. What happens to CFCs in the upper atmosphere? The
What Evidence Did Susan Solomon Discover That Convinced The Scientific Community That CFCs Were Causing Ozone Depletion? What evidence did Susan Solomon discover that led NASA ozone-modeler Paul Newman to reject his hypothesis in favor of her polar cloud hypothesis? The level of ClO in the stratosphere supported the hypothesis that UV-B breaks down CFCs,
What Is Ozone Layer Depletion And Its Effects? Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. … UV rays also affect plant growth, reducing agricultural productivity. What do you
What Does The Stratosphere Protect Us From? The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet’s surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has
How Does CFC Destroy The Ozone Layer? Gaseous CFCs can deplete the ozone layer when they slowly rise into the stratosphere, are broken down by strong ultraviolet radiation, release chlorine atoms, and then react with ozone molecules. See Ozone Depleting Substance What destroyed the ozone layer? Chlorofluorocarbons (CFCs) are a class of chemical refrigerants that
How Does CFC React With Ozone? Once in the atmosphere, CFCs drift slowly upward to the stratosphere, where they are broken up by ultraviolet radiation, releasing chlorine atoms, which are able to destroy ozone molecules. … When sunlight returns in the spring, the chlorine begins to destroy ozone. Why are CFCs so reactive with ozone?
What Is The Problem With Ozone Depletion? Ozone layer depletion causes increased UV radiation levels at the Earth’s surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders. What is ozone depletion causes and effects? Ozone depletion is primarily caused by human
