Which layer of the atmosphere is the first to absorb sun radiation and what is the Earth's ozone layer responsible for absorbing from the sun?
The troposphere is the first layer of the atmosphere to absorb sun radiation. It is the lowest layer of the atmosphere, extending from the Earth's surface to about 6 miles (10 kilometers) high. The troposphere is where all of the Earth's weather occurs, and it is also where most of the atmosphere's gases are located.
The Earth's ozone layer is responsible for absorbing ultraviolet (UV) radiation from the sun. The ozone layer is a thin region of the stratosphere, located about 15 to 35 kilometers above the Earth's surface. Ozone is a molecule made up of three oxygen atoms. It is a very effective absorber of UV radiation, which is harmful to life on Earth.
UV radiation can cause sunburn, skin cancer, and other health problems. It can also damage plants and animals. The ozone layer protects us from the harmful effects of UV radiation by absorbing most of it before it reaches the Earth's surface.
In addition to absorbing UV radiation, the ozone layer also plays a role in regulating the Earth's temperature. The ozone layer heats the stratosphere by absorbing UV radiation. This heating helps to create the temperature gradient that drives the Earth's weather systems.
The ozone layer is a vital part of the Earth's atmosphere, and it is important to protect it from depletion. Human activities, such as the release of certain chemicals into the atmosphere, can damage the ozone layer. However, international agreements have been put in place to reduce the release of these chemicals, and the ozone layer is slowly recovering.
A significant portion of the Sun's ultraviolet (high-energy, shortwave) radiation is absorbed by ozone (O3) in the upper atmosphere (the stratosphere). The absorption of ultraviolet by the ozone layer is critical to all life on Earth. The atmosphere absorbs 23 percent of incoming sunlight while the surface absorbs 48. The atmosphere radiates heat equivalent to 59 percent of incoming sunlight; the surface radiates only 12 percent. In other words, most solar heating happens at the surface, while most radioactive cooling happens in the atmosphere. The ozone layer in the stratosphere absorbs a portion of the radiation from the sun, preventing it from reaching the planet's surface. Most importantly, it absorbs the portion of UV light called UVB. UVB is a kind of ultraviolet light from the sun (and sun lamps) that has several harmful effects. Stratosphere contains much of the ozone in the atmosphere. The increase in temperature with height occurs because of absorption of ultraviolet (UV) radiation from the sun by this ozone. Temperatures in the stratosphere are highest over the summer pole, and lowest over the winter pole.Layer of atmosphere which absorbs UV light radiations is known as ozonosphere. It is a region of Earth's stratosphere. This region contains high concentrations of ozone in comparison to other parts of the atmosphere. Ozonosphere is mainly found in the lower portion of the stratosphere. Higher up, in the stratosphere, the ozone layer absorbs solar ultra-violet radiation and affects how much of the Sun's heat is radiated back into space. The ozone layer shields us from the harmful effects of excessive UV radiation, which can lead to sunburn, skin cancer and eye damage. Atmospheric ozone has two effects on the temperature balance of the Earth. It absorbs solar ultraviolet radiation, which heats the stratosphere. It also absorbs infrared radiation emitted by the Earth's surface, effectively trapping heat in the troposphere.A freed oxygen atom then combines with another oxygen molecule to form a molecule of ozone. There is so much oxygen in our atmosphere, that these high-energy ultraviolet rays are completely absorbed in the stratosphere.
