- The ozone layer is a deep layer in the stratosphere, encircling the Earth, that has large amounts of ozone in it. The layer shields the entire Earth from much of the harmful ultraviolet radiation that comes from the sun.

Atmosphere of Earth The next layer, extending about 15-60 km is called the stratosphere. 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, though the thickness varies seasonally and geographically. The ozone layer protects the earth from the suns UV Rays.

Where Is the Ozone Layer Located? The ozone layer is located in the stratosphere, a region of the atmosphere that is about 10 to 50 kilometers above the Earth. The stratosphere consists of approximately 90 percent ozone. Ozone has the chemical formula O3.

- Best Answer: ozone layer 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.est Answer: ozone layer 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.

- 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. The remaining ozone is in the lower region of the atmosphere, which is commonly called the troposphere. The figure (above) shows an example of how ozone is distributed in the atmosphere.zone thus plays a key role in the temperature structure of the Earth's atmosphere. Without the filtering action of the ozone layer, more of the Sun's UV-B radiation would penetrate the atmosphere and would reach the Earth's surface.

- Note that most of the ozone is in the lower stratosphere. The ozone layer resides at an altitude of about 12 to 15 miles (20 to 25 kilometers) above sea level. It acts as a shield by absorbing biologically active ultraviolet light (called UV-B) from the sun.

- The ozone layer is a concentration of ozone molecules in the stratosphere. About 90% of the planet's ozone is in the ozone layer. The layer of the Earth's atmosphere that surrounds us is called the troposphere.The stratosphere, the next higher layer, extends about 10–50 kilometers above the Earth's surface.Stratospheric ozone is a naturally occurring gas that filters the sun's ultraviolet (UV) radiation.ost atmospheric ozone is concentrated in a layer in the stratosphere, about 15–30 kilometers above the Earth's surface. Ozone is a molecule containing three oxygen atoms. It is blue in color and has a strong odor. Normal oxygen, which we breathe, has two oxygen atoms and is colorless and odorless.

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.

What is the chemical formula for the ozone that protects us from UV rays? The Ozone Hole. 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.

How does the atmosphere protect us from ultraviolet rays? The ozone layer or ozone shield refers to a region of Earth's stratosphere that absorbs most of the Sun 's ultraviolet (UV) radiation.

Glossary of Geography Terms and Definitions The ozone layer is a concentration of ozone molecules in the stratosphere. About 90% of the planet's ozone is in the ozone layer. The layer of the Earth's atmosphere that surrounds us is called the troposphere.The stratosphere, the next higher layer, extends about 10–50 kilometers above the Earth's surface.he Ozone Layer. The Earth's atmosphere is divided into several layers. The lowest region, the troposphere, extends from the Earth's surface up to about 10 kilometers (km) in altitude. The next layer, the stratosphere, continues from 10 km to about 50 km.

- More detail. The ozone layer is the product of very short wave Ultraviolet light (UV-B) breaking apart oxygen molecules. When ozone is formed, it serves to block energetic UV (UV-B) that other molecules don't, and acts to moderate day / night temperature swings a little bit.here is also ozone in the lower troposphere, but the ozone layer in the stratosphere contains helpful ozone that blocks much of the ultraviolet radi … ation. Without this layer, life on earth would be very difficult.

Basic Information about Ozone What is ozone? Ozone is a gas composed of three atoms of oxygen (O3). Ozone occurs both in the Earth's upper atmosphere and at ground level. Ozone can be good or bad, depending on where it is found. Good Ozone

- The ozone layer is a layer of ozone particles scattered between 19 and 30 kilometres (12 to 30 miles) up in the Earth's atmosphere, in a region called the stratosphere.The concentration of ozone in the ozone layer is usually under 10 parts ozone per million.Without the ozone layer, UV radiation would not be stopped from entering the Earth's atmosphere and arriving at the surface, causing untold damage to most living species.he concentration of ozone in the ozone layer is usually under 10 parts ozone per million.

What is Ozone Layer? These ozone molecules form a gaseous layer in the Earth’s upper atmosphere called stratosphere. This lower region of stratosphere containing relatively higher concentration of ozone is called Ozonosphere. The Ozonosphere is found 15-35 km (9 to 22 miles) above the surface of the earth.

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.

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.he troposphere extends from the Earth 's surface to between 12 and 20 kilometers above sea level and consists of many layers.

- Ozone gas forms a layer all around the earth high in the stratosphere. It serves as a vital and effective protective barrier from the sun's ultraviolet rays. In recent years, scientists have sounded alarms internationally about the depletion of the ozone layer, citing chemical pollution as the major cause.

An Overview    of Ozone Depletion in the Stratosphereby scientist and author    Rod Jenkins This is also known as the ozone layer because of the critical role that ozone plays there in protecting the earth from ultraviolet radiation. The stratosphere, or ozone layer, is located approximately 6 to 30 miles above the earth’s surface.
