What is the term for gases produced by aerosols and manufacturing?
Introduction. Chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and aerosols are very important greenhouse gases. CFCs, HFCs, and PFCs are all human made and are not produced by any other process but our activities. CFCs were first synthesized in 1928 by Thomas Midgley, Jr.
What gases are known to destroy the ozone layer?
Ozone depleting substances are chemicals that destroy the earth’s protective ozone layer….They include:
- chlorofluorocarbons (CFCs)
- carbon tetrachloride (CCl4)
- methyl chloroform (CH3CCl3)
- hydrobromofluorocarbons (HBFCs)
- hydrochlorofluorocarbons (HCFCs)
- methyl bromide (CH3Br)
- bromochloromethane (CH2BrCl)
What’s the meaning of greenhouse gas?
Greenhouse gases are gases in Earth’s atmosphere that trap heat. They let sunlight pass through the atmosphere, but they prevent the heat that the sunlight brings from leaving the atmosphere. The main greenhouse gases are: Water vapor. Carbon dioxide.
How hydrocarbons deplete the ozone layer?
Ultraviolet Radiation A type of hydrocarbons that are nonreactive, nonflammable organic molecules in which both chlorine and fluorine atoms replace some of the hydrogen atoms. Use of CFCs is one of the primary causes of stratospheric ozone depletion. A form of oxygen in which three atoms of oxygen occur together.
What do you mean by ozone layer depletion?
Ozone layer depletion means the thinning of the ozone layer present in the upper atmosphere. That is harmful to nature and the atmosphere. Ozone layer depletion is one of the major problems for the atmosphere and also for all the living beings including the flora and fauna of this earth.
Why it is called greenhouse effect?
In short: it is the natural process that warms the Earth’s surface. The process is called the greenhouse effect because the exchange of incoming and outgoing radiation that warms the planet works in a similar way to a greenhouse. Because the air inside the greenhouse naturally stays warmer than the air outside.
Are hydrocarbons ozone depleting?
Glossary. A type of hydrocarbons that are nonreactive, nonflammable organic molecules in which both chlorine and fluorine atoms replace some of the hydrogen atoms. Use of CFCs is one of the primary causes of stratospheric ozone depletion.
Do hydrocarbons destroy ozone?
HFC emissions cause increased warming of the stratosphere, speeding up the chemical reactions that destroy ozone molecules, and they also decrease ozone levels in the tropics by accelerating the upward movement of ozone-poor air. “HFCs are, in fact, weak ozone-depleting substances.”
