The correct sequence of events related to ozone layer depletion is: C, D, B, E, A
-
C. Fridge brought to the house: Refrigerators (fridges) are brought into houses, containing chlorofluorocarbons (CFCs) as cooling agents.
-
D. Chlorofluorocarbons used as cooling agent: CFCs, used in refrigerators and other applications, release chlorine into the atmosphere when they break down.
-
B. High levels of chlorine and bromine compounds in the stratosphere: Chlorine and bromine compounds from CFCs rise to the stratosphere, where they contribute to ozone layer depletion.
-
E. Depletion of ozone layer: Ozone layer depletion occurs due to the presence of chlorine and bromine compounds, leading to a reduction in ozone concentration.
-
A. Ultraviolet radiation causes skin cancer: With the depletion of the ozone layer, there is an increased penetration of ultraviolet (UV) radiation, which can lead to harmful effects such as skin cancer.
