WebWhat is ozone layer depletion? How does it occur? The thinning of the ozone layer present in the upper atmosphere is called ozone layer depletion. Some chemical compounds release chlorine and bromine, which in exposure to high ultraviolet light causes the depletion of ozone. What are ozone-depleting substances? Give examples. WebCredit: NASA. An ozone molecule consists of three oxygen atoms (its chemical symbol is O 3 ), and its maximum concentration in the stratosphere is a result of ultraviolet radiation's interactions with oxygen gas (O 2 -- the gas that humans need to breathe). When oxygen gas absorbs ultraviolet radiation, the oxygen atoms split.
