The ozone layer protects life on Earth by absorbing harmful ultraviolet radiation.

Ozone is a molecule with three oxygen molecules.It is in the upper atmosphere and it protects living organisms by keeping UV rays from reaching the earth's surface. Ozone (O3) is a triatomic, molecule, consisting of three oxygen atoms.

Stratospheric ozone is “good” because it protects living things from ultraviolet radiation from the sun. Ground-level ozone, the topic of this website, is “bad” because it can trigger a variety of health problems, particularly for children, the elderly, and people of all ages who have lung diseases such as asthma.

In the stratosphere, there is a layer called ozone. It is formed by the dissociation of oxygen molecules into individual oxygen atoms. ... At an altitude of 25 km (16 miles), ozone gets to its peak density, which is just a few parts per million. The ozone is a thin gas forming a protective layer above the earth surface.

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").

How Can Ozone Be Both Good and Bad? 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.

The atmosphere helps to protect living organisms from genetic damage by solar ultraviolet radiation, solar wind and cosmic rays. The current composition of the Earth's atmosphere is the product of billions of years of biochemical modification of the paleoatmosphere by living organisms.

The troposphere generally extends to a level about 6 miles up, where it meets the second layer, the stratosphere. The stratosphere or "good" ozone layer extends upward from about 6 to 30 miles and protects life on Earth from the sun's harmful ultraviolet (UV) rays.

In addition to their own resiliency, living things and the cells they are made of are protected from excessive amounts of UV radiation by a chemical called ozone. A layer of ozone in the upper atmosphere absorbs UV radiation and prevents most of it from reaching the Earth.

Our Protective Atmosphere Our Sun is a source of energy across the full spectrum, and its electromagnetic radiation bombards our atmosphere constantly. However, the Earth's atmosphere protects us from exposure to a range of higher energy waves that can be harmful to life.

What is the ozone layer? The ozone layer is the common term for the high concentration of ozone that is found in the stratosphere between 15 and 30km above the earth's surface. It covers the entire planet and protects life on earth by absorbing harmful ultraviolet-B (UV-B) radiation from the sun.

While ozone high in our atmosphere is important for protecting people from the sun's ultraviolet radiation, at ground level it can be a significant health threat. Ground level ozone, or smog, is formed from a chemical reaction between nitrogen oxides and volatile organic compounds in the presence of heat and sunlight.

The ozone layer, located in Earth's stratosphere miles above the ground, shields the planet from much of the sun's damaging ultraviolet radiation.

The atmosphere protects us from exposure to higher energy radiation that can be harmful to life – i.e. X-Ray and Gamma Rays. As the energy passes through the atmosphere, it interacts with the molecules and particles present in the atmosphere.

The answer is ozone layer. The ozone layer or ozone shield refers to a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. ... Ozone is transparent to most UV-A, so most of this longer-wavelength UV radiation reaches the surface, and it constitutes most of the UV reaching the Earth.

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 hole itself has a minor cooling effect (about 2 percent of the warming effect of greenhouses gases) because ozone in the stratosphere absorbs heat radiated to space by gases in a lower layer of Earth's atmosphere (the upper troposphere).
