What Causes the Ozone Hole to be at its Biggest?

When is the ozone hole at its biggest each year?

a Southern Hemisphere; fall

b Southern Hemisphere; spring

c Northern Hemisphere; fall

d Northern Hemisphere; spring

Answer:

The ozone hole is at its biggest in the Southern Hemisphere during spring.

The correct answer is b) Southern Hemisphere; spring. The ozone hole in the Earth's atmosphere is primarily located over Antarctica and reaches its maximum extent in the Southern Hemisphere's spring, which is from September to November. During this time, various environmental factors contribute to the depletion of the ozone layer, resulting in the ozone hole being at its biggest.
