Why is ozone depletion worse in Antarctica?
Ozone depletion is worse in Antarctica because of the presence of polar stratospheric clouds, which provide a surface for chemical reactions that break down ozone molecules. Additionally, the extreme cold temperatures in Antarctica contribute to the formation of these clouds, making the ozone depletion more severe in this region.
What clouds are formed high in the atmosphere?
The highest clouds are polar mesospheric clouds, which, at heights from 76,000 to 85,000 m (altitude) are much higher than other types of clouds, such as cirrus and cumulonimbus. Cumulonimbus can exceptionally reach 23,000 m at the very top of a peaked formation, but these clouds normally form mainly within the 2,000 to 16,000 m range. Cirrus clouds, at a maximum height of about 18,000 m in tropical zones, are also much lower than polar mesosphericclouds.
Very cold region that lies above the ozone rich layer of stratosphere?
42. ---- The ozone layer is located in the bottom of the stratosphere, so just above the ozone layer is still stratosphere. See the link below to the entry at Wikipedia for the stratosphere, that shows the various layers above the stratosphere (mesosphere, thermosphere, exosphere)
A low level cloud?
A low level cloud is a cloud that forms below 6,500 feet (2,000 meters) in the atmosphere. These clouds are typically composed of water droplets and are often associated with precipitation. Examples of low level clouds include stratus clouds, cumulus clouds, and stratocumulus clouds.
What is name is given to low altitude winter clouds?
mistFoganother name for it is fogFog.Fogvery low clouds are called stratus clouds ;PFogfogits called fog...mist, fogFOG
What are polar stratospheric cloud?
Polar Stratospheric clouds or PCS's are clouds present in the poles. These act as the base for ozone depleting reactions.
What polar stratospheric promotes ozone distruction?
Polar Stratospheric Clouds are called PSC's. They act a catalysts for ozone depletion.
What are polar stratospheric clouds and how it aids in ozone depletion?
Polar stratospheric clouds or PSC's are formed at cold regions. These form the base for the various ozone depleting reactions at the poles.
What is the relationship between polar statoshperic clouds to ozone depletion?
Polar Stratospheric clouds are formed at poles. They act as a base for ozone depletion.
Why des the formation of polar stratospheric clouds impact ozone destruction?
It does impact the ozone depletion. They act as a base for the depletion of ozone.
Where is ozone depletion the worst?
The ozone depletion is worst at the poles. It is due to the low temperature there. The Polar Stratospheric Clouds are formed at the poles.
Break down of ozone layer is promoted by?
The breakdown of ozone layer is promoted by the CFC's. PSC's i.e. Polar Stratospheric Clouds also take part in it.
Does the temperature in Antarctica allow clouds to form?
You'll see clouds in Antarctica that you can only see in polar environments, including noctilucent clouds -- electric-blue-coloured, and polar stratospheric clouds or PSCs, also known as nacreous clouds, These clouds are formed very high -- 50,000 to 80,000 feet -- in the atmosphere, and appear due to a mix of ice crystals and meteoric dust. this means that they are not formed the way that most clouds over earth are formed. These clouds form due to sunlight and not to temperature.
Why is ozone depletion worse in Antarctica?
Ozone depletion is worse in Antarctica because of the presence of polar stratospheric clouds, which provide a surface for chemical reactions that break down ozone molecules. Additionally, the extreme cold temperatures in Antarctica contribute to the formation of these clouds, making the ozone depletion more severe in this region.
Why ozone depletion is very related to polar region?
Ozone depletion is particularly related to the polar regions because of the unique climatic and atmospheric conditions found there. During winter, polar regions experience long periods of darkness and extremely cold temperatures, which create polar stratospheric clouds. These clouds enhance chemical reactions that break down ozone molecules. Additionally, polar vortexes (large-scale cyclonic winds) in the stratosphere confine the depleted ozone, resulting in the formation of the infamous "ozone hole."
What is it called when its really colorful in the sky in Antarctica?
There are several 'really colorful' events in the skies over the Antarctic continent, in addition to sunlight, starlight and moonlight. When the sun is up, you can see sun dogs, that Wikipedia describes as: "... the scientific name parhelia (singular parhelion), are an atmospheric phenomenon that creates a pair of bright spots of light on either side on the sun, often co-occurring with a luminous ring or halo." Sun dogs are also visible in less polar, but high-latitude geographies on earth. When there is no sun, Aurora Australis are visible during the dark periods, and from Wikipedia: "The aurora is produced by solar wind particles guided by Earth's field lines to the top of the atmosphere." When there have been no sunrises, once the sun does rise -- once again from Wikipedia, below -- "Polar stratospheric clouds or PSCs, also known as nacreous clouds, are clouds in the winter polar stratosphere at altitudes of 15,000 to 25,000 meters (49,000 to 82,000 ft)."
Where is thinning of ozone most evident?
The thinning of ozone layer is most pronounced at the poles of the earth. It is because of the low temperature of the low temperature there. The ozone depleting reactions are carried on the polar stratospheric clouds i.e. the PSC's. these PCS's require minimum temperature for their formation which is possible only on the poles.
