What is Stratosphere definition/concept

The space around us can be layered for better organization and understanding. In this sense, the Earth’s atmosphere is divided into four layers: troposphere, stratosphere, mesosphere and thermosphere. The temperature in the different layers is the determining factor for making this distinction.

The ozone layer is found in the stratosphere

The troposphere reaches up to 20 kilometers in height and in it there is a decrease in temperature the greater the height; this drop occurs as a consequence of the distance from the heat source, the Earth. The set of human activities is related to the troposphere.

The stratosphere starts from 20 kilometers high. In it there is a gradual increase in temperature due to the absorption of the Sun’s ultraviolet rays. In this layer is the ozone layer (ozone molecules absorb part of the solar radiation and this increases the temperature). It should be noted that the ozone layer has the function of protecting the atmosphere. In other words, it allows the preservation of life conditions on Earth by acting as a protective shield that prevents ultraviolet radiation.

The destruction of the ozone layer

Some products used by people (so-called halocarbons) cause the destruction of ozone in the stratosphere. This causes a progressive depletion of the ozone layer, unprotecting the Earth from the harmful effects of the Sun.

The release of halocarbons into the stratosphere is intensifying the depletion of the ozone layer. Among the chemical elements used by humans that threaten the stability of the atmosphere are chlorofluorocarbons, also known as CFCs. CFCs remain active in the stratosphere for many years before decomposing and destroying the ozone layer. Most CFCs come from air conditioning systems, freezers, aerosols and synthetic foams.

The destruction of the ozone layer causes the sun’s rays to reach the Earth’s surface causing irreparable damage to the environment and to the health of human beings

Because of this, it is advisable not to expose yourself to the sun’s rays for a long time, otherwise you may get some diseases such as skin cancer, cataracts or immune problems.

Of course, plants and animals also suffer negative consequences due to the weakening of the ozone layer (the effect of ultraviolet rays can change the chemical composition of plants, which can affect the food chain).
