ozone
First, all aeroplanes do leave a carbon foot print. Second, a nuclear bomb would do horrific damage to the ozone layer ( that's why nuclear testing is banned). Lastly, since no one proved that alien exist their spaceships are not real, but if they are I would imagine that they would do damage to the ozone layer.It should be pointed out that a carbon foot print has nothing at all to do with the thinning caused by a lack of sunlight to a layer of our atmosphere. CO2 may be a greenhouse gas, but has nothing to do with the ozone layer.Nuclear bombs could do damage to this layer, but that is not why they are banned. They do damage in many other ways.Rockets to space dump water vapor, and some of them dump chlorine containing molecules. These all tend to decrease ozone levelsAircraft dump water vapor, and decrease oxygen levels. These all tend to decrease ozone levels. This is a much stronger effect than for rockets, since many more tons of fuel are involved annually.Nuclear bombs loft large quantites of contaminants to the upper atmosphere, but very few of them are not fully oxidized. Some water vapor is lofted ahead of the mushroom cloud, and this will do some damage. Thankfully these do not occur often.CFCs are extremely stable, and the only place they can go away, is where sunlight is strong enough to break them down. Unfortunately, this is where the sunlight is strong enough to make ozone... the ozone layer. So where we have dumped CFCs to the atmosphere since the early 1900s, it will take a while for them to leave the system. And Nature is continually adding Her bit to this loading as well... plants do also make / release chloromethane, especially when burned.
clouds
they really affect the stratosphere because as they get there the ultraviolet rays decompose them to release chlorine the real ozone killer~chlorine forms an unstable compound with ozone which later reduces it to oxygen destroying the ozone layer quickly because chorine can be active of a century.
This process is called the greenhouse effect. Solar radiation from the sun passes through Earth's atmosphere and warms the surface. Some of this heat is then trapped by greenhouse gases in the atmosphere, such as carbon dioxide and methane, which act like a blanket by preventing the heat from escaping back into space.
The three types of aerosols measured by NASA researchers are sea salt aerosols, dust aerosols, and black carbon aerosols. Sea salt aerosols are produced by the breaking of ocean waves, dust aerosols result from dust storms and other sources of dust in the atmosphere, and black carbon aerosols come from the combustion of fossil fuels and biomass burning.
ozone
The ozone layer present in the stratospheric region of the atmosphere is being destroyed by certain chemicals. These chemicals are CFCs.
Chlorofluorocarbons (CFCs) are chemicals that have been primarily responsible for damaging the protective ozone layer in the Earth's stratosphere. When released into the atmosphere, CFCs break down and release chlorine atoms that then react with ozone molecules, leading to ozone depletion.
The ozone layer was depleted from the actions of CFCs (chlorofluorocarbons) released into the atmosphere last century. CFCs were used in aerosols and fridges and escaped into the air where the winds gradually moved them all around the world and up to the ozone layer. There chlorine broke from the CFCs and destroyed the ozone.
Ozone layer is destroyed by the continues use of CFCs. They react with ozone to decompose it and deplete the layer.
Chlorofluorocarbons (CFCs) are primarily responsible for the reduction of the ozone layer in the atmosphere. When CFCs are released into the atmosphere, they can break down ozone molecules, leading to the thinning of the ozone layer.
CFCs (chlorofluorocarbons) destroy the ozone layer allowing harmful radiation to reach the earth.
The ozone layer, located in the stratosphere, has been partly destroyed by certain chemicals like chlorofluorocarbons (CFCs) and halons. This depletion has led to an increase in harmful ultraviolet radiation reaching the Earth's surface, which can have detrimental effects on human health and the environment.
They are carried by westerlies. They destroy the ozone.
1. CFCs help in refrigeration but destroy the ozone layer when released into the atmosphere
The hole in the ozone layer is primarily caused by human activities releasing chemicals called chlorofluorocarbons (CFCs) into the atmosphere. These CFCs break down ozone molecules, leading to the thinning of the ozone layer.
CFCs break down ozone in the atmosphere when they are exposed to ultraviolet radiation. This causes the CFC molecules to release chlorine atoms, which then react with ozone molecules, leading to the destruction of the ozone layer.
