Understanding Global Warming and Ozone Layer

The video from MakeMeGenius.com explains global warming and the greenhouse effect, highlighting the role of greenhouse gases in maintaining Earth's temperature. It discusses human activities that increase these gases, leading to global warming. The video also covers the ozone layer's role in protecting Earth from harmful UV rays and how human actions are damaging this protective layer. Solutions to mitigate these impacts are suggested.

What would happen to Earth's temperature without greenhouse gases?

• It would remain the same

• It would fluctuate wildly

• It would freeze

• It would become extremely hot

How do human activities increase greenhouse gases in the atmosphere?

• By using solar panels

• By driving cars and using factories

• By planting more trees

• By conserving energy

What is the effect of cutting down trees on greenhouse gases?

• It has no effect

• It increases greenhouse gases

• It decreases carbon dioxide levels

• It increases oxygen levels

What is the role of the ozone layer in Earth's atmosphere?

• To absorb ultraviolet rays

• To produce oxygen

• To reflect sunlight

• To trap heat

What are the harmful effects of ultraviolet rays?

• They cause skin cancer and eye cataracts

• They increase plant growth

• They cause global warming

• They improve air quality

Which substances are responsible for damaging the ozone layer?

• Carbon dioxide

• Methane

• Nitrogen

• CFCs

What can individuals do to help protect the ozone layer?

• Drive more cars

• Cut down more trees

• Use products without CFCs

• Use more air conditioners

What happens when there are holes in the ozone layer?

• More UV rays reach Earth

• The Earth becomes cooler

• Less sunlight reaches Earth

• More oxygen is produced
