Question

What is the ozone layer and what is its importance?

Answer 1

it it a layer of gas name ozone in the sky it protects us from harmful ultraviolet rays.

Answer 2

ozone layer is composed of O3....And its purpose is as simple as this.....TO PROTECT US from meteors,,heat,extreme radiation and foreign bodies entering the earth....That's how important it is....So please be one of the rare people to value it's existence and try to save it...

Answer 3

Ozone layer is layer of ozone gas which is found 50km above sea level. It protects us from ultraviolet rays which have high wavelength and smaller then VIBGYOR's violet rays. they causes skin diseases and destroys reproductive cells. They are been stopped by ozone layer.

Answer 4

The ozone in the earth's upper atmospheric, the stratosphere, moderates and reduces ultraviolet light. preventing much of it from getting to the ground level. When this ozone is depleted, more ultraviolet light passes to the ground level.

On one hand, long wave ultraviolet light striking the skin produces natural vitamin D in the body, which helps metabolize calcium into bone tissue. On the other hand, short wave ultraviolet light is ionizing radiation which can produce skin cancer.

It may be that the dosage of ultraviolet light that constitutes benefical exposure, and what constitutes excessive exposure may be overlapping. Both the benefits and risks may be present at the same time. It can be seen that both less ozone and more ozone in the upper atmosphere have detriments and benefits simultaneously.

On the ground level ozone is a respiratory irritant, and can aggravate the respiratory tract and also asthmatic conditions.

Ozone is a more powerful oxidant than oxygen, and is weaker only than fluorine, and a handful of radicals. Ozone is intenioinally generated and used in commerical and municipal applications for sterilization, flocculation, oxidation, and taste and odor reduction

Answer 6

The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3).

Ozone layers are important for us because it doesn't allow the ultraviolet rays (coming from the sun) to come to us.

Due to the pollutions the ozone layer is becoming thinner,it result is increasing the temp. of the earth.

So Ozone layer is important for living things.

Answer 7

The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 93-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on earth.[1] Over 91% of ozone in earth's atmosphere is present here.[1] "Relatively high" means a few parts per million—much higher than the concentrations in the lower atmosphere but still small compared to the main components of the atmosphere. It is mainly located in the lower portion of the stratosphere from approximately 10 km to 50 km above Earth's surface, though the thickness varies seasonally and geographically.[2] The ozone layer was discovered in 1913 by the French physicists Charles Fabry and Henri Buisson. Its properties were explored in detail by the British meteorologist G. M. B. Dobson, who developed a simple spectrophotometer that could be used to measure stratospheric ozone from the ground. Between 1928 and 1958 Dobson established a worldwide network of ozone monitoring stations which continues to operate today(2008). The "Dobson unit", a convenient measure of the total amount of ozone in a column overhead, is named in his honor.

Answer 8

well, the ozone layer is made up of a pure form of oxygen, which protects the Earth from the harmful ultraviolet rays of the sun. This ozone layer is important because it shields us against possible massive outbreaks of different kinds of cancer, such as skin cancer and cataracts and death.

Answer 9

The ozone layer is a layer in Earth's atmosphere which contains relatively high concentrations of ozone (O3). This layer absorbs 93-99% of the sun's high frequency ultraviolet light, which is potentially damaging to life on earth.

Answer 10

Ozone is greenhouse gas which resides in the atmosphere for two reasons.

1. It does not allow the earth heat to loss during night, so the temperature of earth does not fall so much that it becomes inhabitable.

2. It does not allow the excess heat (including ultra violet radiations) of the sun to come to earth to destroy the earth's life.

Now-a-days due to the production of gases like CFC and other atmospheric pollution, this ozone layers have become thinner, so the average day temperature has risen in the last couple of years
