- 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.

Ozone layer Ozone layer. The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet (UV) radiation. It contains high concentrations of ozone (O3) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

Ozone layer The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains high concentrations of ozone in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer contains less than 10 parts per million of ozone, while the average ozone concentration in Earth's atmosphere as a whole is about 0.3 parts per million. The ozone layer is mainly found in the lower portion of the stratosphere, from approximately 20 to 30 kilometres (12 to 19 mi) above Earth, although its thickness varies seasonally and geographically.

Where is the Ozone Layer Located Ozone layer hole. Image credit: NASA. The Ozone Layer is the portion of the atmosphere that contains high levels of the oxygen molecule ozone. This molecule plays an important role acting as a natural UV shield for the Earth. You may wonder where is the ozone layer located to play such a vital role so effectively. The Ozone layer is actually located in the stratosphere in a region that is 10 to 50 km above the Earth.

Why is the ozone layer important for life on Earth? Where is Ozone present?-The Ozone layer is present in two layers of the atmosphere. What is the importance of ozone layer? The sun radiates a huge variety of radiations such as ultraviolet radiations which are very harmful to the human body. It is the ozone layer which helps to absorb the ultraviolet radiation rays.

Why is the ozone layer important? In the 1980s, scientists discovered a hole in the ozone layer from human use of CFCs gases used in refrigerators. These gases were banned and the hole in the ozone layer is being repaired.

Unit 12 (Ryan) Earth's History Why is the ozone layer important for Earth's life forms? The ozone layer is important for Earth's life forms because it protects Earth from harmful ultraviolet radiation. This made the environment able to support more complex life forms. 2.) Describe the role of cyanobacteria in changing Earth's early atmosphere. Cyanobacteria helped in changing Earth's atmosphere by adding an abundance of oxygen to it. To this day cyanobacteria's account for 20% to 30% of photosynthesis today.

- The ozone layer is typically thicker over the poles than over the equator for three reasons. First, there is a lack of sunlight during an arctic winter to break it down. Second, seasonal weather systems and wind patterns in the upper atmosphere push more ozone toward the poles in winter.ost of the earth's ozone is contained in the stratosphere, a layer of the atmosphere 1040 km above the surface of the earth. The amount of ozone in the stratosphere is fairly constant when viewed globally. However, it changes throughout the year and from one place to another.

Unit 12 (Ryan) Earth's History Explain two reasons why having an oxygen-rich atmosphere is important for life on Earth. 1.) We need an oxygen-rich atmosphere for life on Earth to breathe and survive. We need oxygen to simply be alive. 2.) We need an oxygen-rich atmosphere (creating the ozone layer) to protect life on Earth from harmful ultraviolet radiation.

The Ozone Layer The ozone layer is the Earth's natural sunscreen, filtering out harmful ultraviolet (UV) rays from the sun. UV rays can cause damage to humans and other forms of life. Although the ozone layer is high up in the atmosphere, chemical substances used at the surface of the planet can damage it.

- The OZONE LAYER which lies in Stratosphere (16 to 48 kilometers above earth's surface) protects us from harmful UV radiation. Ozone layer help us by trapping harmful radiation from the sun. Ultraviolet(UV) rays are harmful rays which come from the sun. Ozone layer is made up of #O_3# or three atom of oxygen. When UV rays of 230 to 320 nm hit the ozone layer, #O_3# absorbs its energy and gets converted into #O_2# & then #O#.

Tropospheric ozone Ozone (O 3) is a constituent of the troposphere (it is also an important constituent of some regions of the stratosphere commonly known as the ozone layer). The troposphere extends from the Earth 's surface to between 12 and 20 kilometers above sea level and consists of many layers. Ozone is more concentrated above the mixing layer, or ground layer. Ground-level ozone, though less concentrated than ozone aloft, is more of a problem because of its health effects. Photochemical and chemical reactions involving it drive many of the chemical processes that occur in the atmosphere by day and by night.

Why is the ozone layer important for life on Earth? The ozone layer is very important for life on earth. It protects us from harmful UV rays that can have serious effects on biodiversity, animals and people’s health, including skin cancer and eye cataract.

Why is the ozone layer important to humans? Ozone present in the stratosphere of the earth's atmosphere is  called as good ozone. It protects us from the harmful UV light of  the sun.Ozone present in the troposphere i … s also called as bad  ozone. It is also a   green house gas. It is the major constituent of the urban smog.

High School Earth Science/The Atmosphere Ozone in the Upper Atmosphere Makes Life on Earth Possible [edit]. Ozone is a molecule composed of three oxygen atoms, (O 3). Ozone in the upper atmosphere absorbs high energy ultraviolet radiation (UV) coming from the Sun. This protects living things on Earth's surface from the Sun's most harmful rays.

Formation of the Ozone Layer High in the atmosphere, some oxygen (O 2) molecules absorbed energy from the Sun's ultraviolet (UV) rays and split to form single oxygen atoms. These atoms combined with molecular oxygen (O 2) to form ozone (O 3) molecules, which are very effective at absorbing UV rays. The thin layer of ozone that surrounds Earth acts as a shield, protecting the planet from irradiation by UV light. The amount of ozone required to shield Earth from biologically lethal UV radiation, wavelengths from 200 to 300 nanometers (nm), is believed to have been in existence 600 million years ago.

How Does the Ozone Layer Affect Life on Earth The ozone layer is essentially Mather Earth’s safety net, residing some 50 kilometres above the planet’s surface. Created from O3, or ozone gas, it is up to 20 kilometres thick and 90 per cent of this gas can be found up on the Earth’s stratosphere.

Layers of Earth's Atmosphere Concluding Thoughts. Ozone is found in two different layers of the atmosphere - the troposphere and the stratosphere. The stratospheric ozone, or good ozone, protects life on earth from harmful effects of the sun's UV rays. We have good reason to be concerned about the thinning of the ozone layer in the stratosphere. Tropospheric ozone, or bad ozone, is an air pollutant that damages human health, vegetation, and many common materials.

What is Ozone Layer? Ozone layer is a deep layer in earth’s atmosphere that contain ozone which is a naturally occurring molecule containing three oxygen atoms. These ozone molecules form a gaseous layer in the Earth’s upper atmosphere called stratosphere.zone depletion occurs when destruction of the stratospheric ozone is more than the production of the molecule. The scientists have observed reduction in stratospheric ozone since early 1970s. It is found to be more prominent in Polar Regions. There are two regions in which the ozone layer has depleted.

- The Ozone Layer The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3).This layer absorbs 97-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on earth.zone layer thickness is expressed in terms of Dobson units, which measure what its physical thickness would be if compressed in the Earth's atmosphere. In those terms, it's very thin indeed. A normal range is 300 to 500 Dobson units, which translates to an eighth of an inch-basically two stacked pennies.

- The Ozone layer protects us from the harmful ultraviolet radiations of the sun which can cause serious damage to the human life causing eye cataract, skin cancer and depressed immune system. Basically UV-rays. UV-rays convert Oxygen (O2) to Ozone (O3).

Instead, think of it in terms of parts per million concentrations in the stratosphere (the layer six to 30 miles above the Earth's surface).
