What causes the ozone layers hole to get bigger?

Answer 1

Contaminants such as water vapor (Nature and Man), CFCs (Man), and bromine compounds (Nature and Man) cause the equilibrium concentration of ozone to decrease. This makes the ozone hole (once it forms) to be larger, as compared to ages when these contaminants were not present.

Answer 2

There are two primary causes associated with the changes in size of what we call our "holes" in the ozone layer.

The first, and most important cause is a lack of sunlight. There are two locations where this issue occurs. The largest location is over the Antarctic, at the end of it's winter months. A smaller, similar situation occurs over the Arctic during the end of the winter there. When the sun returns to these areas, the situation quickly disappears.

The second known reason for changes in our ozone layers thickness is due to solar variation. The largest known thinning of our layer occurred in 1859 due to a solar flare.

As long as we have oxygen in our atmosphere and sunlight hitting that oxygen, physics will keep doing what it is supposed to and converting that oxygen into ozone.

Answer 3

The hole in the ozone layer gets bigger due to the release of harmful chemicals called chlorofluorocarbons (CFCs) that break down ozone molecules. These CFCs are found in products like aerosol sprays and refrigerants, and when they reach the stratosphere, they react with ozone, causing the hole to expand. Efforts to reduce the use of CFCs through international agreements like the Montreal Protocol have helped slow down the depletion of the ozone layer.

Answer 4

The ozone layer is not getting bigger. The ozone hole is.

Answer 5

No one is really sure.
