Does Oxygen molecules stop UV radiation or is it only Ozone molecules that can?
Feaniro
UV is commonly broken up into three rough groupings called UV-A, UV-B, and UV-C. Oxygen and nitrogen absorb UV-C and break apart. Some of the oxygen forms ozone. Ozone absorbs UV-C and some UV-B and breaks apart. Ozone also absorbs UV-B and reradiates it randomly. UV-A (the sutff good for tanning) is pretty much just passed thru to the surface of the Earth. So some UV is blocked by oxygen (UV-C), just not any of UV-B, which directly strikes our DNA since we are largely transparent to UV-B and DNA is not.

Which part of the solar radiation is absorbed by the ozone layer?
The ultraviolet radiation is absorbed by the ozone layer. The ozone molecules do not allow only the ultraviolet radiations to pass through.
What atoms make an ozone molecule?
Ozone is a molecule composed of three oxygen atoms. The chemical symbol of ozone is O3 as the symbol of oxygen atoms is O.Most ozone found in our atmosphere is formed by an interaction between oxygen molecules and ultraviolet radiation emitted by the sun. (Oxygen molecules make up about 21% of all gases in the earth's atmosphere; they consist of two atoms of oxygen and are therefore labeled O2).When ultraviolet (UV) radiation hits an oxygen molecule, it may cause the molecule to break apart into single atoms of oxygen (O2 + UV -> O + O). These atoms are very reactive, and a single oxygen atom can combine with a molecule of oxygen to form ozone (O2+ O -> O3).The individual ozone molecules make up what we call the ozone layer. It is not, however, an especially thick layer there are usually less than three ozone molecules for every ten million molecules of air. That is why ozone is known as a trace gas, meaning that only trace (very small) amounts are present. We are fortunate that these small amounts make a big difference.
Which molecule do not absorb microwave radiation?
Ozone does not absorb microwave. It only absorbs UV.
What chemicals make up bad ozone?
Ozone is a molecule composed of three oxygen atoms (unlike the normal oxygen molecules which contains only two oxygen atoms). All ozone has the same composition, there is only one kind of ozone. Whether ozone is considered to be good or bad depends upon the location of the ozone, not the composition. Ozone at high altitudes is good, because it protects us from ultraviolet radiation from the sun. Ozone at ground level is bad, because it is harmful to our health if we inhale it.
What happens during the ozone cycle?
Short Answer: It is the continuous formation of ozone from oxygen, and the decay of that ozone back to oxygen. Oxygen absorbs UV-B or more energetic radiation (most commonly from our Sun), and dissociates into two separate oxygen atoms. Some of these singlet oxygen atoms combine with an oxygen atom to form ozone. Ozone has several decay paths, but all leave an oxygen molecule at the end: # Ozone encounters another ozone or singlet oxygen and only oxygen results. Ozone is inherently unstable and this does happen. # Ozone absobs UV-B or more energetic radiation (again from the Sun most commonly) and dissociates into an oxygen molecule and a singlet oxygen atom (some few of which will make ozone again). # Ozone encounters the long list of things that ozone will attack, and ozone loses a single oxygen atom to the reaction. Only #3 removes net oxygen from the "pool" of oxygen. There are additional pathways of forming ozone, where a nitrogen molecule temporarily stores the singlet oxygen, until an oxygen molecule is encountered and the payload can be delivered. There are mechanisms that block this "handoff" also, and they also remove oxygen from the "pool".

Is ozone only found in the troposphere?
No, ozone is found in all layers of the atmosphere. In the troposphere, ozone is considered a pollutant, because it contributes to smog and gives a bitter taste to the air, but in the stratosphere and ionosphere, ozone absorbs ultraviolet radiation and reduces our risk of sunburn and skin cancer. Ozone is naturally produced when radiation strikes oxygen and ionizes it, and the oxygen ions recombine into ozone.

What chemicals make up the ozone layer?
The ozone layer is made up of ozone molecules only. These molecules are reactive in nature.
How is an oxygen molecule different than a ozone molecule?
An ozone molecule has 3 atoms of oxygen (O3), compared to the two-atom molecule (O2) that we breathe.
Does UVA radiation get absorbed by ozone?
It does not. It only absorbs UV-B radiation.
Are there any objects in the ozone layer?
No they are not. the complete ozone layer contains the ozone molecules only.
What is the d layer made out of?
The ozone layer is made up of pure ozone molecules only. The molecules absorb the UV-C molecules.
What occurs when sunlight hits the ozone layer?
The layer is heated. Some oxygen, nitrogen, and ozone molecules are destroyed. Ozone is made. This is how the ozone layer returns after the polar winters deplete the layer. Lack of sunlight is the major issue with ozone depletion and the ONLY method that allows the ozone to return.
