The stratosphere ____.

Question

BlackTom AI · Accepted Answer

The question asks about the stratosphere and provides several statements to assess.
Option 1: 'has higher levels of nitrogen and oxygen than the troposphere' In reality, the atmospheric composition (mainly N2 and O2) is fairly uniform throughout the standard layers; there isn’t a simple claim that the stratosphere has higher levels of these gases than the troposphere. The statement is misleading because it implies a significant compositional difference that isn’t supported by basic atmospheric science.
Option 2: 'is where most of the human contact with air pollutants occurs' This is incorrect because the majority of air pollutants interact with the atmosphere in the troposphere, not primarily in the stratosphere. The stratosphere has far lower concentrations of pollutants due to limited vertical mixing with the polluted troposphere and greater distance from surface sources.
Option 3: 'contains the atmosphere’s protective ozone layer' This is a true and well-established fact: the ozone layer is located largely within the stratosphere, where ozone molecules absorb and help block much of the Sun’s ultraviolet radiation, providing vital protection for living organisms.
Option 4: 'is characterized by temperatures that decrease with altitude' This statement describes the troposphere, where temperature generally falls with height. In the stratosphere, temperatures actually rise with altitude in the lower to mid-stratosphere due to ozone absorption of UV radiation, so this option is incorrect.
Option 5: 'is where the photochemical smog forms' Photochemical smog forms primarily in the lower atmosphere (troposphere) where sunlight and pollutants mix near the surface. The stratosphere is far above typical pollution sources, so this statement is inaccurate.
