The ozone layer is a layer of ozone high up in the Earth's atmosphere stratosphere, between approximately 10 kilometres and 50 kilometres above Earth’s... |
Ozone is a gas that is present in the ozone layer in the stratosphere of the Earth. There, it absorbs almost all ultraviolet light which is harmful to... |
portion of the stratosphere with a high concentration of ozone, called the ozone layer. The ozone layer is 10 to 50 kilometers above the ground. It filters... |
ozone depletion. CFCs are greenhouse gases. An alternative to chlorofluorocarbons is hydrofluorocarbons (HFCs). These do not destroy the ozone layer or... |
work on the ozone layer and climate change. Crutzen died on 28 January 2021 at the age of 87. "Paul Crutzen, who shared Nobel for ozone work, has died"... |
Stratosphere (category Layers of Earth's atmosphere) by the ozone layer which absorbs some UV radiation from sunlight. The absorbed radiation is converted to heat. This differs from the lower layer, the troposphere... |
Chlorofluorocarbons more and more, also because it is less harmful to the ozone layer. Very often, mixes of propane and butane are sold. Pixie Gas Archived... |
was one of the scientists who discovered that there was a hole in the ozone layer in the Earth's atmosphere. He is the first Mexican to receive the Nobel... |
cool things. Some refigerants escape into the atmosphere and damage the ozone layer, so chemists have developed new refrigerants in another example of applied... |
of oxygen molecules. The newly independent oxygen atoms create ozone in the ozone layer. This short article about chemistry can be made longer. You can... |
sunlight is absorbed at a very high altitude by the ozone layer. Recent and ongoing destruction of ozone in high altitudes caused by human influence—mostly... |
the stratosphere. HFC do not contain chlorine which is harmful for the ozone layer. HFC survive in the atmosphere between two and forty years. CFC can stay... |
Air pollution (section Ozone hole) concrete. A global concern is the hole in the ozone layer in the stratosphere. The Earth's ozone layer protects life from the Sun's harmful ultraviolet... |
do scientists suppose that these chemicals reach the altitude of the ozone layer to adversely affect it?". Sci. Am. "Refrigerant blends to challenge hydrocarbon... |
academy said. “Surface chemistry can even explain the destruction of the ozone layer, as vital steps in the reaction actually take place on the surfaces of... |
up. The burning of most substances is bad for the environment and the ozone layer because it can let off greenhouse gases such as carbon dioxide. Hydrogen... |
Melanoma is prominent in New Zealand and Australia due to the hole in the ozone layer and the many beaches. Melanoma that has metastasised (spread beyond the... |
List of R-phrases (redirect from R59: Dangerous for the ozone layer) long-term adverse effects in the environment R59: Dangerous for the ozone layer R60: May impair fertility R61: May cause harm to the unborn child R62:... |
from the Ozone layer at the top of the stratosphere. There is little water vapor and other substances in this layer. Airplanes fly in this layer because... |
magnetic field. Storms of solar particles would otherwise strip away the ozone layer which protects us from ultraviolet radiation. Sometimes we see aurorae... |
