Relatively high concentrations of ozone. This layer absorbs 93-99% of the suns UV light, which is potentially harming to life on earth.
The ozone layer is made of the usual constituents of atmosphere, ~78% nitrogen, ~21% oxygen, a bit of argon, and way down on the list is ozone at about 9 ppm (rather than ~0.05 ppm like is found at Earth's surface). The ozone layer does not contain as much water vapor as the lower atmosphere does, which helps ozone stay longer.
An ozone is composed of three oxygen atoms (O3) rather than the usual two (O2).
Ozone is made up of ozone molecules. It is present as ozone layer.
The ozone layer is a layer of gas. It is made up of ozone gas.
Ozone layer is made up of ozone. It is an allotrope of oxygen.
Ozone layer is made up of ozone molecules. It is present in the stratospheric region.
The man made objects in ozone layer are CFC's. They are harmful to ozone.
Ozone layer depletion is the reduction in ozone layer. It is due to man made ODS.
Ozone is continually made by the Sun. Ozone made at Earth's surface does not survive to reach the ozone layer.
Ozone layer is made of O2 only. It is because ozone is an allotrope of oxygen.
ozone layer disappears due to man made chemicals. These are CFC's that damage the ozone layer.
Ozone layer is a layer of ozone molecules. It is destroyed by man made CFC's.
Ozone layer is depleting because of CFC gases. It has made holes in Ozone layer.
It was made there.
