New ozone hole found above the Arctic

A small ozone hole has been detected above the Arctic, covering less than 1 million square kilometers, compared to the larger Antarctic hole. The European Space Agency (ESA) attributes this to strong westerly winds from the polar vortex trapping cold air over the North Pole. When the polar winter ended, sunlight triggered ozone depletion, forming this unusual mini hole. This Arctic ozone hole formation differs from the Antarctic one, which occurs annually due to cold temperatures and human pollution.

What is the approximate size of the ozone hole discovered above the Arctic?

• Less than 1,000,000 square kilometers

• 20,000,000 square kilometers

• 5,000,000 square kilometers

• 10,000,000 square kilometers

What atmospheric phenomenon trapped cold air over the North Pole, contributing to the Arctic ozone hole?

• El Niño

• Polar vortex

• Jet stream

• Monsoon winds

What event triggered the depletion of ozone over the Arctic?

• A meteor shower

• A volcanic eruption

• A solar eclipse

• The first sunlight after polar winter

How does the formation of the Arctic ozone hole differ from the Antarctic one?

• It is triggered by the end of polar winter

• It occurs due to human pollution

• It happens every year

• It is caused by volcanic activity

What are the main factors contributing to the annual appearance of the Antarctic ozone hole?

• Ocean currents and volcanic eruptions

• Warm temperatures and solar flares

• High humidity and forest fires

• Cold temperatures and human pollution
