Question
While ozone (O3) can be a harmful contributor to smog in the lower atmosphere, in the upper atmosphere a layer of ozone helps toMultiple choice question.decrease acid deposition by binding to sulfur and nitrogen oxides.mediate the effects of eutrophication.increase rates of photosynthesis by tying of oxygen (O2).block damaging ultraviolet radiation from the sun.
Solution
The correct answer is: block damaging ultraviolet radiation from the sun.
Here's why:
-
Ozone in the upper atmosphere, also known as the ozone layer, acts as a shield and absorbs most of the sun's harmful ultraviolet (UV) radiation. If this layer is depleted, more UV rays can reach the earth's surface, causing harm to living organisms.
-
The other options are incorrect because:
- Ozone does not decrease acid deposition by binding to sulfur and nitrogen oxides. Acid deposition is primarily caused by human-made emissions of sulfur and nitrogen compounds which react in the atmosphere to form acids, which then fall to earth.
- Ozone does not mediate the effects of eutrophication. Eutrophication is a process driven by the enrichment of water by nutrient salts that causes structural changes to the ecosystem such as increased production of algae and aquatic plants.
- Ozone does not increase rates of photosynthesis by tying of oxygen (O2). Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that can later be released to fuel the organisms' activities.
