Why is ozone concentration higher at the poles?
Understand the Problem
The question is asking for an explanation regarding the reasons behind higher ozone concentrations at the poles, and provides multiple choice options to consider.
Answer
Ozone moves from the tropics to polar regions, increasing concentration in spring.
Ozone concentration is higher at the poles during spring due to increased transport of ozone from the tropics to the polar regions in late fall and winter.
Answer for screen readers
Ozone concentration is higher at the poles during spring due to increased transport of ozone from the tropics to the polar regions in late fall and winter.
More Information
The ozone layer's higher concentrations in polar regions during spring result from natural atmospheric circulation patterns that transport ozone from the tropics.
Tips
Confusing the role of transport with production, which primarily occurs in tropical regions.
