If the atmospheric proportion of oxygen becomes very high, what would be the most likely effect on natural balance?
Answer and explanation
Correct answer: Combustion intensity may increase
Oxygen supports oxidation and combustion. If its atmospheric concentration became much higher than normal, many materials would burn more readily and fires could become more intense, disturbing ecological and atmospheric balance. Therefore, option A is the most reasonable effect. High oxygen would not make solar heat zero, convert water vapour into a permanent gas, or transform the ozone layer into nitrogen, so B, C and D are invalid.
