  2. It accelerates the chemical reactions that destroy ozone.

  3. It prevents the transport of ozone-depleting substances to the stratosphere.

  4. It has no significant impact on ozone depletion.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The polar vortex acts as a barrier, trapping ozone-depleting substances within the polar regions and preventing their dispersal to other parts of the globe.

Multiple choice

What is the primary reason for the seasonal variation in ozone depletion?

  1. Changes in the Earth's rotation speed

  2. Variations in solar radiation intensity

  3. Fluctuations in atmospheric temperature

  4. Variations in the strength of the polar vortex
