where is the ozone layer harmful?
448937
Ozone occurs in two layers of the atmosphere. The layer closest to the Earth's surface is the troposphere. Here, ground- level or “bad” ozone is an air pollutant that is harmful to breathe and it damages crops, trees and other vegetation.

Describe the difference between good and bad ozone. Good ozone is in the stratosphere and protects the earth from harmful ultraviolet radiation. Bad ozone is in the troposphere and is a pollutant. ... global warming is a process caused the atmospheric absorption of infrared heat energy radiated from the earth's surface.

Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth's surface (see the figure below). Ozone is a molecule that contains three oxygen atoms. At any given time, ozone molecules are constantly formed and destroyed in the stratosphere.

Ozone is a particularly effective absorber of UV radiation. As the ozone layer gets thinner, the protective filter activity of the atmosphere is progressively reduced. Consequently, the people and the environment are exposed to higher levels of UV radiation, especially UVB.

90% of the planet's ozone is in the "ozone layer" which exists in the lower level (20-25 kilometres above sea level) of the stratosphere. The stratosphere is the region of the atmosphere which exists between 10 and 50 kilometres above the surface of the earth.

Yet in a new study published in Atmospheric Chemistry and Physics, scientists report that one crucial section of the ozone layer still seems to be declining steadily. The ozone layer resides in the stratosphere, the region of atmosphere from 10 to 50 kilometers above Earth's surface.

Solution(By Examveda Team) The ozone layer restricts ultraviolet radiation. The Ozone layer which is present in the Earth's atmosphere protects it by restricting from UV or Ultraviolet radiation, the dangerous rays contained by Sun.

The ozone hole is basically a human-caused hole in the ozone layer above the South Pole during the Southern Hemisphere's spring. The ozone layer, which lies high up in the atmosphere, shields us from harmful ultraviolet (UV) rays that come from the Sun.

The ozone which is produced naturally in Stratosphere is called stratospheric ozone. It protects us from the harmful UV Ray of the sun. Ambient ozone is that type of ozone which is found in ground level of earth. This type of ozone is actually air pollutant.

How is Ozone Harmful? ... When inhaled, ozone can damage the lungs. Relatively low amounts can cause chest pain, coughing, shortness of breath and throat irritation. Ozone may also worsen chronic respiratory diseases such as asthma and compromise the ability of the body to fight respiratory infections.

Chlorofluorocarbons (CFCs), hydrochlorofluorocarbons (HCFCs) and halons destroy the earth's protective ozone layer, which shields the earth from harmful ultraviolet (UV-B) rays generated from the sun. CFCs and HCFCs also warm the lower atmosphere of the earth, changing global climate.

The sun 's ultraviolet rays are still bearing down on you. Stratospheric ozone acts as a shield by absorbing potentially harmful ultraviolet (UV) radiation which would otherwise reach the earth 's surface. But the sun 's harmful ultraviolet (UV) rays reflect off water making you burn faster.

The ozone layer is depleted in two ways. Firstly, the ozone layer in the mid-latitude (e.g. over Australia) is thinned, leading to more UV radiation reaching the earth. ... Secondly, the ozone layer over the Antarctic, and to a lesser extent the Arctic, is dramatically thinned in spring, leading to an 'ozone hole'.

Their long lifetimes in the atmosphere mean that some end up in the higher atmopshere (stratosphere) where they can destroy the ozone layer, thus reducing the protection it offers the earth from the sun's harmful UV rays. CFCs also contribute to Global Warming (through "the GreenhouseEffect").

Ozone is a gas in the atmosphere that protects everything living on the Earth from harmful ultraviolet (UV) rays from the Sun. ... The ozone layer acts as a shield to absorb the UV rays, and keep them from doing damage at the Earth's surface.

Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). This region of the atmosphere is called the stratosphere. The ozone in this region is commonly known as the ozone layer.

Additional Information. Most atmospheric ozone is concentrated in a layer in the stratosphere, about 9 to 18 miles (15 to 30 km) above the Earth's surface (see the figure below). Ozone is a molecule that contains three oxygen atoms.
