factors) or nonliving variables (abiotic factors),
such as water, soil, climate, light, and oxygen.
All interacting biotic and abiotic factors
together make up an ecosystem. Organisms and their
environment constantly interact, and both are

Our Radiant Planet- Depletion of the Ozone Layer
Ozone is a relatively unstable form of molecular
oxygen containing three oxygen atoms produced when
upper-atmosphere oxygen molecules are split by
ultra violet light. Stratospheric ozone is found
in a broad band, extending generally from 15 to 35
km above the earth. Although the ozone layer is
surprisingly thin, it acts as a protective shield
to the earth, as it filters out most of the
harmful solar ultraviolet radiation (in particular
UV-B) that ...
