Understanding Ozone and SAGE III

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

• To regulate Earth's temperature

• To provide oxygen for breathing

• To support plant growth

• To block harmful UV rays from the sun

What was the significant discovery made by the British Antarctic Survey in 1985?

• The increase in greenhouse gases

• The depletion of the ozone layer above Halley Bay

• The presence of life on Mars

• The discovery of a new planet

What is the main purpose of the Montreal Protocol?

• To enhance global trade

• To regulate greenhouse gas emissions

• To promote space exploration

• To control the production of ozone-depleting chemicals

How does SAGE III monitor the ozone layer?

• By collecting soil samples

• By using the Sun and Moon as light sources

• By tracking weather patterns

• By measuring Earth's temperature

What challenge does SAGE III face in monitoring ozone recovery in the tropics?

• Lack of advanced technology

• Changes in greenhouse gases like CO2

• Interference from other satellites

• Limited funding for research
