The United Nations' (UN) International Day for the Preservation of the Ozone Layer is celebrated on September 16 every year. This radiation is dangerous to living organisms on Earth.
ozone layer: The ozone layer screens out the sun's harmful ultraviolet radiation. The ozone layer plays an important role in the protection of the biosphere from dangerous ultraviolet radiation of the sun. Total ozone levels are at their annual peak in the late winter and early spring. The ozone layer acts as a natural filter, absorbing most of the sun's burning ultraviolet (UV) rays.Stratospheric ozone depletion leads to an increase in UV-B that reach the earth's surface, where it can disrupt biological processes and damage a number of materials.. This long essay about Depletion of Ozone Layer is suitable for students of class 7, 8, 9 and 10, and also for competitive exam aspirants. 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 surface.The exact amount of ozone varies, depending on the seasons and the location. poisonous: She has lots of poisonous plants in her garden. A diminished ozone layer allows more radiation to reach the Earth's surface.
The fact that UV-B can cause biological effects is well demonstrated by the familiar sunburn that follows overexposure to the sun. This event commemorates the date of the signing of the Montreal Protocol on Substances that Deplete the Ozone Layer in 1987. It also forms the temperature structure of the stratosphere and therefore has a direct influence on the general circulation and the surface climate. poison: The cat was killed by rat poison. With the CFC-ban in place, atmospheric levels of chlorine are beginning to decline and the ozone layer is, we hope, on its way to recovery. However it is also at this time when man-made substances can lead to enhanced ozone depletion in the stratosphere. The ozone layer is important because it filters harmful ultraviolet radiation as it travels from the sun to the surface of the Earth.
Answer:
The ozone layer effectively blocks almost all solar radiation of wavelengths less than 290 nanometres from reaching Earth's surface, including certain types of ultraviolet (UV) and other forms of radiation that could injure or kill most living things.
Explanation:
If You Want More so.....Most ozone resides in the stratosphere (a layer of the atmosphere between 10 and 40 km above us), where it acts as a shield to protect Earth's surface from the sun's harmful ultraviolet radiation. With a weakening of this shield, we would be more susceptible to skin cancer, cataracts and impaired immune systems.
Or
Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun. Without the layer of ozone in the atmosphere, it would be very difficult for anything to survive on the surface. (Think of a very bad sunburn, only much worse!)
