Question

over which of the following land masses an ozone hole is observed?​

Answer 1

Explanation:

The low total ozone values over Antarctica in September constitute the “ozone hole” in 2009. Since the 1980s, the ozone hole in late winter/early spring represents the lowest values of total ozone that occur over all seasons and latitudes (see Q10).

Answer 2

Answer:

The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere. The ozone layer is the part of the Earth's atmosphere which contains relatively high concentrations of ozone gas, which is an inorganic molecule with the chemical formula O3. Ozone is a pale blue gas with a pungent (chlorine-like) smell.
