Chlorofluorocarbons (CFCs) are present in very low concentrations in the Earth's atmosphere, typically measured in parts per trillion (ppt) or parts per quadrillion (ppq). The percent composition of CFCs in the atmosphere is extremely low, usually less than 1 part per trillion.
Nitrogen makes up about 78% of Earth's atmosphere.
Chlorofluorocarbons (CFCs) build up in the atmosphere when they are released from products like refrigerants and aerosols. Once in the atmosphere, CFCs break down and release chlorine atoms, which then catalyze the destruction of ozone molecules in the ozone layer.
Approximately 90% of the chlorine in the atmosphere is attributed to natural sources, such as volcanoes and sea spray. The remaining 10% is mostly due to human activities, primarily from the use of chlorofluorocarbons (CFCs) and other industrial processes.
CFCs (chlorofluorocarbons) currently make up less than 1% of greenhouse gases in the Earth's atmosphere.
Over 80% of the chlorine found in the stratosphere comes from chlorofluorocarbons (CFCs). These compounds can break down in the upper atmosphere, releasing chlorine atoms that can then participate in ozone depletion reactions.
The earth's atmosphere at sea level.
Jupiter's atmosphere is 90 percent hydrogen and 10 percent helium. There are also some small amounts of sulfur, ammonia, water vapor and methane.
None, if the Wkipedia entry is to be believed. See link http://en.wikipedia.org/wiki/Atmosphere#Composition
any of a class of compounds of carbon.
Nitrogen makes up about 78% of Earth's atmosphere.
The percentage of argon depends on whether you refer to argon in the atmosphere or the total composition of the earth.
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
Jupiter's atmosphere is comprised of about 90 percent hydrogen and 10 percent helium. Jupiter is a gas giant and has no real solid surface.
Chlorofluorocarbons (CFCs) build up in the atmosphere when they are released from products like refrigerants and aerosols. Once in the atmosphere, CFCs break down and release chlorine atoms, which then catalyze the destruction of ozone molecules in the ozone layer.
78 percent Air is mostly gas The air in Earth's atmosphere is made up of approximately 78 percent nitrogen and 21 percent oxygen.
Hydrogen and helium make up 99 percent of Jupiter's atmosphere. These two gases are the most abundant elements in the planet's composition.
