Which Gas Does Not Destroy Ozone Layer? [Solved]

Countries around the globe agreed not to use ozone-depleting chemicals in order to prevent the destruction of the ozone layer. The 1985 Vienna Convention for the Protection of the Ozone Layer and the 1987 Montreal Protocol on Substances that Deplete the Ozone Layer formalized this agreement. The universal ratification of both the Montreal Protocol and the Vienna Convention was achieved in 2009. The protocol covers substances known as “controlled substances”. The main substances include chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs), halons, carbon tetrachloride, methyl chloroform and methyl bromide. Their ozone destruction potential (ODP), is the measure of how each substance damages the ozone layers 🙌🙈 [1]
Earth’s ozone Layerozone LayerThe area of the stratosphere which contains most of the atmospheric ozone. In the stratosphere the ozone layer is approximately 15-40km (10-25 miles) high above Earth’s surface. Ozone-depleting substances (ODS), which are used to deplete this layer, will result in higher UVB levels. Cause increased skin Cancers, cataracts, and possible damage to certain marine organisms, plants and plastics. The science page ( offers much more detail on the science of ozone depletion. This shield protects all living things from harmful ultraviolet radiation. However, human activity has damaged it. There is less protection by ultraviolet light (UV), lightultraviolet light (UV) light. Ultraviolet radiation, which has wavelengths that are shorter than visible lights, requires less ozone-layer. UVA, UVB and UVC are the three main UV bands produced by sunlight. Ozone does not absorb UVA. UVB is mostly absorbed into ozone. However, some UVB can reach the Earth. UVC can only be absorbed completely by normal oxygen and ozone. NASA provides more information on their web site ( This could eventually lead to more severe skin conditions and damage of crops. Cancer and cataract rates. [2]

The ozone layerozone LayerThe area of the stratosphere that contains the majority of atmospheric ozone. It is approximately 10-15 kilometers (25-25 miles) high above the Earth’s top, and lies in the stratosphere. Ozone depleting chemicals (ODS) can lead to a decrease in this layer. This will increase UVB levels and cause skin cancers and cataracts as well as potential damage to marine organisms, plants and plastics. The science page ( offers much more detail on the science of ozone depletion. Is a concentration of ozone molecules in the stratospherestratosphereThe region of the atmosphere above the troposphere. It extends approximately 10 km to 50 km in height. Airliners fly to the lower stratosphere. At higher altitudes, the stratosphere becomes warmer. This is actually due to ozone absorption ultraviolet radiation. It is believed that the warmer air is still in the upper stratosphere while cool air is found in the lower stratosphere. This is The layer of the Earth’s atmosphere that surrounds us is called the tropospheretroposphereThe region of the atmosphere closest to the Earth. While the height of the troposphere is approximately 10 km above the ground, it varies according to latitude. Nearly all weather is found in the troposphere. Mt. Everest is 8.8km high, making it the tallest mountain in Earth. The troposphere has a lower temperature than the atmosphere. Warm air rises and then cools down, returning to Earth. The process is called convection. It refers to large air movements which mix the troposphere extremely efficiently. The stratosphere is the second higher layer and extends approximately 6 to 31 mi (or 10 to fifty kilometers) above Earth’s Surface. Find out more about the layer of ozone.

Sharon Couch Provide more information. The radiative forcing and greenhouse gases. Climate warming Earth by the Sun GHGs are an important part of the environment. The natural abundances of GHGs in Earth’s atmosphere absorb outgoing infrared radiation, trapping heat in the atmosphere Warming the surface. Water vapor is the most significant natural GHG. Water vapor is the most important natural GHG. Greenhouse effect, Earth’s surface would be much colder than current conditions. Since 1750 (the start of the Industrial Era), significant increase in atmospheric concentrations of both short-lived GHGs has been caused by human activities. This led to the warming of Earth’s surface and associated climate changes. This group contains carbon dioxide (CO2) and methane(CH4). Ozone-depleting substances (ODSs) and their substitutes make up a large fraction of the halocarbons in today’s atmosphere. An increase in these gases due to human activity causes more infrared radiation outgoing to be absorbed, and then reemitted to the surface. This further warms the atmosphere. This change in Earth’s energy balance caused by human activities is called a radiative forcing A climate changing or more precisely, climate forcing. This measure of energy imbalance occurs at the upper troposphere, or the Tropopause. It is measured in watts per square mile (W/m2) units. As the radiative forcing rises, so does climate change potential. [4]
Both bromine and chlorine have similar atomic structures and both can deplete the ozone layer. If a single element’s atom is in direct contact with an Ozone molecule, the additional oxygen atom is stripped to make a more stable molecular molecule. The molecule can be either hypochlorite (or hypobromite) ion. Because they are far from being inert, every hypochlorite and each hypobromite react with another ozonemolecule to create two oxygen molecules. This leaves the chlorine or bromine free to restart the process. This is how a single bromine or chlorine atom can transform thousands of ozone molecules to oxygen.
