Ozone Layer
The ozone layer is a crucial layer in the Earth's atmosphere that absorbs and blocks out harmful ultraviolet light that can damage Earth.

Not on your life. The highest layers of the atmosphere are the coldest,
and the hottest season in the US occurs at the time when the Earth is
farthest away from the sun.
How was the ozone layer formed in stratosphere?
The ozone layer was formed in startosphere by the action of UV rays. these radiations just decomposed oxygen into oxygen atom which combines with oxygen to form ozone.
What is the ozone layer beneficial to all life on earth?
The ozone layer beneficial to all life due to it's properties. These properties include the absorbtion of UV rays.
How does the troposphere and stratospher protect us?
They contain the ozone gas. It protects us from the harmful UV rays of the sun.
What gas blocks the ozone layer that absorbs ultraviolet radiation?
The CFC's block the ozone layer by destroying it. The destruction is caused by the reaction of gases with ozone.
What is carbon dioxide in the greenhouse effect?
Carbon dioxide is the main greenhouse gas. It also causes global warming.
What caused the antarctic hole?
The Antarctic ozone hole is primarily caused by human activities, specifically the release of ozone-depleting substances such as chlorofluorocarbons (CFCs) and halons. These chemicals break down ozone molecules in the stratosphere, leading to the formation of the ozone hole. Efforts to reduce the production and emission of these substances have helped to stabilize and partially heal the ozone layer.
If there's a hole in the ozone layer at the antarctic why don't all the penguins have cancer?
penguins can't get cancer because of there bodies........................................................ ---- An ozone hole occurs where the atmosphere receives no UV-C (and consequently no UV-B) from the Sun. So there is no UV-B to give the penguins cancer when the hole is present. Note that penguins most commonly stand straight up (unlike seals, etc.), which presents minimum aspect to the Sun when UV-B will be at its peak.
What mandates the use of non ozone depleting substances?
The Montreal Protocol mandates the use of non-ozone depleting substances to address the depletion of the ozone layer. It is an international agreement that aims to phase out the production and consumption of ozone-depleting substances, such as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), which harm the ozone layer. By transitioning to non-ozone depleting substances, countries can protect the ozone layer and mitigate the harmful effects of UV radiation on human health and the environment.
How Kyoto protocol become ozone friendly?
Kyoto is a protocol for environment changes. It has recently shifted its focus to ozone depletion too.
How the growing industrial activity is responsible for depletion of water table?
Industrial activity can lead to the depletion of the water table through excessive water extraction for manufacturing processes and cooling purposes. Additionally, pollution from industrial runoff can contaminate groundwater, making it unsuitable for consumption and further reducing available water sources. The overall increase in demand for water by industries can stress local water resources, leading to a decline in the water table level.
What implication does destruction of the stratospheric ozone layer have for Earth?
Destruction of ozone layer will cause the UV rays to enter the earth. These radiations are fatal for life on earth.
What layer of the atmosphere protects living things from too much radiation from the Sun?
The "ozone layer" in the stratosphere contains triple molecules of oxygen (O3, ozone) that absorb the energy of UV rays from the Sun, limiting the amount of UV that reaches the surface. The ozone layer occurs between 20 and 30 kilometers above the Earth (60,000 to 100,000 feet).
Is the stratosphere the closest layer to the earths surface?
No. the layer that actually reaches the surface is the troposphere.
Why is the ozone layer beneficial to all life on earth?
Ozone layer is beneficial to all life on earth. It protects the flora and fauna from the UV rays.
Do one ozone layer cover all the earth?
The ozone is present inside the atmosphere. And yes, it covers the whole of the earth.
Why do ozone gas protects us by the sun?
Ozone gas protects us from the UV rays. These are fatal UV rays from the sun.
What gas in the atmosphere is used to form ozone?
Oxygen.
Virtually all of the ozone in the "Ozone Layer," which is in the stratosphere and not the troposphere where we live, is formed from oxygen atoms and oxygen molecules.
If light with a wavelength shorter than 240 nm is absorbed by a molecule of oxygen, O2, then the oxygen molecule can split into two oxygen atoms. A photon of UV light normally cleaves the oxygen molecule, but an X-ray may also cause the cleavage. Thus the first step in the formation of ozone is:
O2 + hν (<240 nm) ---> 2 O.
The reaction that produces ozone proceeds very slowly because it requires that three species collide at the same time. The reaction to form ozone is:
O. + O2 + M ---> O3 + M, where M is usually a molecule of nitrogen, but it could be a helium atom, an argon atom, or even another oxygen molecule. The formation of ozone is exothermic, meaning that energy is released, and another species, M, is necessary to absorb this excess energy or the ozone just formed or nearly formed may fly apart as a molecule of diatomic oxygen and an oxygen atom.
Some ozone is created from the right cosmic radiation and a molecule of oxygen. An alpha particle and a beta particle with the right kinetic energies may collide with O2 to form helium and a molecule of ozone. The reaction is:
α + β + O2 ---> He + O3
Little to none of the ozone created from pollution, lightning, or from other electrical discharges in the air makes its way up to the Ozone Layer. Ozone is a very powerful oxidizing agent, therefore it is a very reactive species. It readily attacks rubber, causing it to harden and crack like an old rubber band, and it does damage lung tissue. Normally our body can repair any damage faster than it is created, although the elderly, the very young, or persons that are ill are often adversely affected by what is ultimately man-made ozone.
How does ozone protect us from ultraviolent radiation?
Ozone in stratosphere helps to absorb the UV rays. These are the harmful rays of the sun.
How ozone is both beneficial and harmful?
Ozone is beneficial in stratosphere. It acts as a pollutant at ground level.
What does the layer in the upper atmosphere do?
The layer in upper atmosphere is ozone layer. It protects us from UV rays of the sun.
Which layer contains most of the ozone layer And what does it do?
The layer containing most of ozone layer is the stratosphere. This layer protects us from the harmful UV radiations of the sun.
