What Is The Function Of The Stratospheric Ozone Layer? The stratospheric ozone layer is Earth’s “sunscreen” – protecting living things from too much ultraviolet radiation from the sun. The emission of ozone depleting substances has been damaging the ozone layer. What is the function of the stratospheric ozone layer 1 point? Ozone in the stratosphere
Why Do CFCs Deplete 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? But
Why CFCs Are Not Used Anymore? The atmospherically benign HFC refrigerants will remain in production, but CFC and HCFC refrigerants will be phased out. Production of CFCs ceased in 1995. … Because they are so expensive, it may be more economical to convert them to another refrigerant than to replace the refrigeration system. Is CFC
Which Layer Of Atmosphere Gets The Most Affected With Earth’s Air Pollution? The troposphere contains the largest percentage of the mass of the atmosphere relative to the other layers. It also contains some 99 percent of the total water vapor of the atmosphere. Does air pollution affect the ozone layer? The hole in the ozone
Which Of The Following Is A Health Risk Associated With The 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. Which of the following are consequences of ozone
Why Is AC Bad For The Environment? Most air conditioners are fueled by electricity and use a refrigerant that results in a byproduct of gas emissions that cause climate change and deplete the ozone layer. In fact, some studies predict that by 2050, roughly 25 percent of global warming will be caused by air conditioning.
Why Is The Ozone Layer In Antarctica Significant? The very low winter temperatures in the Antarctic stratosphere cause polar stratospheric clouds (PSCs) to form. Special reactions that occur on PSCs, combined with the relative isolation of polar stratospheric air, allow chlorine and bromine reactions to pro- duce the ozone hole in Antarctic springtime. Why is
Why Would A Depleted Ozone Layer Increase The Risk Of Skin Cancer Quizlet? The ozone layer is involved in blocking a substantial amount of the UV from the sun. An increase of UV in areas with depleted ozone would lead to more damage to skin cell DNA and ultimately higher rates of skin cancer. Why
Does Ozone Cover The Earth? The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere around 15–30km above the earth’s surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun. How does ozone protect the life
Is R134a Chlorine Free? R134a was the first chlorine free (ODP = 0) HFC refrigerant that was tested comprehensively. It is now used world-wide in many refrigeration and air conditioning units with good results. As well as being used as a pure substance, R134a is also applied as a component of a variety of blends.
