Question

List the natural causes of Ozone Layer depletion.

Answer 1

Natural causes of ozone layer depletion include:

1. Volcanic eruptions: release gases and particles that can affect ozone chemistry.

2. Sunspots and solar flares: increase the amount of solar radiation, affecting ozone levels.

3. Natural emission of nitrogen oxides: from soil and oceans, which can destroy ozone.

4. Stratospheric winds: can transport ozone-poor air, leading to thinning in certain regions.
