Ozone layer prevents most harmful wavelengths of ______ light from passing through the earth’s atmosphereUltraviolet
The "Dobson unit", a convenient measure of the amount of ozone overhead, is named in his honor. The ozone layer absorbs 97 to 99 percent of the Sun's medium-frequency ultraviolet light (from about 200 nm to 315 nm wavelength), which otherwise would potentially damage exposed life forms near the surface.
Ozone depleting chemicals such as carbon tetrachloride, trichloroethane (also known as methyl chloroform), and bromine compounds known as

Which of the following factor not responsible for land degradation
Land degradation is a process of deterioration or loss of the productive capacity of the soils for present and future, which is majorly induced by human beings. Land degradation is happening at an alarming pace, contributing to a dramatic decline in the productivity of croplands and rangelands worldwide.
Therefore, once a land is destroyed or depleted it is not good for vegetation so the resolution for that is deforestation in order to gain fertile land. So this cannot be the factor responsible for land degradation.
The per capita forestland in the country is only
