ozone layer or ozonosphere‚ region of the stratosphere containing relatively high concentrations of ozone‚ located at altitudes of 12-30 mi (19-48 km) above the earth’s surface. Ozone in the ozone layer is formed by the action of solar ultraviolet light on oxygen. The ozone layer prevents most ultraviolet (UV) and other high-energy radiation from penetrating to the earth’s surface but does allow through sufficient ultraviolet rays to support the activation of vitamin D in humans.

in Hong Kong The ozone layer present in the stratosphere of the Earth is utmost important to us as it protects us from the exposure of ultraviolet rays which leads to several harmful effects. Without the ozone layer‚ human will be more prone to skin cancer and eye cataracts. Ultraviolet rays can also cause harm to marine life by reducing the amount of planktons and consequently depreciates the amount of fishes in the ocean. Besides that‚ the depletion of the ozone layer disrupts the production of

streams down every window‚ Layers of Fear ticks the first box in the list of horror clichés straight from the off. That’s not to say this psychedelic first-person horror doesn’t offer anything unique. Starting out in a seemingly empty 19th-century mansion certainly sets an uncomfortable tone‚ and aided by the rambling narrative of an artist who has completely lost his mind - Layers of Fear consistently unsettles you.

cancer‚ etc. In the year 1985‚ NASA detected the thinning out of the ozone layer leading to the formation of ‘ozone hole’ in Antarctica. Since then the scientists have been regularly monitoring the thickness of the ozone layer. They have found that the thickness of the ozone layer has been decreasing day by day at the alarming rate as a result of the environmental pollution. The main culprits of the serious depletion of ozone layer are found to be the manmade chlorofluorocarbons (CFC’s). These CFC (also

The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer‚ also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to 0.05 ppm in troposphere. It acts as a protective shield for the man‚ animals and plants by filtering out the lethal ultraviolet rays from reaching the earth’s surface. If the ozone layer is not there‚ the harmful ultraviolet rays will reach to the

Discussion Using the Thin Layer Chromatography experiment‚ caffeine was found to be the most polar due to the fact that it stayed closer to the stationary phase. Caffeine contains four amine groups that are extremely polar as a result of the hydrogen bond and amide functional group. Acetaminophen was found to be the second most polar analgesic drug tested. Acetaminophen contains a polar alcohol group on one side and amide group on the other but also includes non-polar functional groups that consisted

Every time 1% of the ozone layer is depleted‚ 2% more UV-B is able to reach the surface of the planet. So in short‚ without the ozone layer everything on earth will burn. The ozone layer is just as important to us as oxygen‚ without it the harmful UV radiation would give us server burns and destroy our delicate ecosystems. Even though there is hard evidence that proves that ozone depletion is harmful for organisms on earth‚ there are a few groups who think that the ozone layer is a “myth” aka doesn’t
