Erosion of Ozone Layer and Global Warming

What are the main causes of ozone depletion?

• Deforestation and land use changes

• Increased carbon dioxide levels

• Natural volcanic eruptions

• The main causes of ozone depletion are chlorofluorocarbons (CFCs) and other ozone-depleting substances.

What role do greenhouse gases play in global warming?

• Greenhouse gases cool the atmosphere, reducing global warming.

• Greenhouse gases only affect weather patterns, not global warming.

• Greenhouse gases have no effect on global temperatures.

• Greenhouse gases trap heat in the atmosphere, leading to global warming.

Name three common greenhouse gases.

• hydrogen, carbon dioxide and nitrogen oxide

• carbon dioxide, methane, nitrous oxide

• oxygen, metane and freons

• argon , carbon dioxide and nitrous axide

How does global warming impact weather patterns?

• Global warming only affects ocean currents, not weather patterns.

• Global warming leads to severe climatic changes and melting of snow in the polar regions of the Earth

• Weather patterns remain unchanged regardless of global warming.

• Global warming leads to cooler temperatures and less rainfall.

How does global warming affect polar ice caps?

• Global warming causes polar ice caps to melt, leading to rising sea levels and disrupted the natural habitat of polar animals

• Global warming leads to increased snowfall in polar regions.

• Polar ice caps have no relation to global temperatures.

• Global warming causes polar ice caps to grow thicker.
