Question details

Which of the following is not true about conditions leading to the Antarctic ozone hole? Reactions that lead to activation of catalytically- inactive forms of chlorine take place on the aqueous surface of PSC crystals. O O Stratospheric ozone (measured in Dobson Units) is usually higher in polar regions than in the tropics. Ozone depletion does not begin until early spring, because light is necessary to photodecompose Cl2 gas to catalytically active Cl atoms. o O The air pressure drops significantly over Antarctica when the temperature drops in winter, and this combined with the rotation of the Earth leads to formation of a vortex in the stratosphere. Polar stratospheric clouds (PSCs) exist over the South Pole year-round. O
