Is The Ozone Layer In The Stratosphere?


The ozone layer is a really important part of the atmosphere. The ozone layer is actually protecting the earth from the sun’s harmful radiation, but now due to many reasons, the layer is losing its actual state, due to both natural phenomena, and human activities, which will end up giving us some really critical situations.

The Ozone Layer

The atmosphere that we witness today formed gradually over a long period of time. The troposphere is the atmospheres’ lowest layer. It begins from the earth’s surface and extends up to 10 km or 6 miles, where the troposphere ends stratosphere begins.

Moreover, from 10 km it stretches up to 50 km or 31 miles. most of the time commercial airplanes fly using the lower part of this layer. And this is the layer where ozone forms itself. A region in the atmosphere, which is between 15 km and 30 km, the ozone layer.

Three oxygen molecules constitute the ozone gas. Over a long period of time, this layer creates as a part of the process. Ozone molecules are constantly created, but the total amount of the gas remains the same.

Absorbing Radiation

The layer keeps the planet cooler by absorbing some percentages of the sun’s radiation. And more than that it absorbs a part of the UV light, which we call UVB.

Moreover, this particular type of UV light is responsible for many harmful effects on the ecosystem, which includes skin cancer, problems in marine life, and harmful effects upon some plants.

The concentration of ozone in the atmosphere varies with many things, like with latitude; its distance from the sun and the climate of that particular region plays an important role here.

Depletion Of The Ozone Layer

There are some chemical compounds that are harmful to the ozone layer, like chlorine or bromine, and then these types of particles interact with the layer in presence of the sun’s UV light, the process of depletion begins. These types of particles are ods(ozone-depleting substances). They are like CFCs, HCFCs, etc.

The risk of losing all the benefits that we are having from the ozone layer is even greater now, because of human activities, though natural phenomena take an important part in this. And that is why in the 1970s CFC is to be ban, but because of many reasons, the global production of CFC continued.

Some natural processes like volcanic eruptions affect the layer indirectly by realizing tiny particles in the atmosphere, which increases chlorine effectiveness on the layer. But all chlorine and bromine sources are not bad for the layer, according to researchers.

You will find the ozone hole in the atmosphere surrounding Antarctica.
