Question 1: What international agreement was established to protect the ozone layer?
- Rio Agreement
- Montreal Protocol
- Kyoto Protocol
Answer: Montreal Protocol
Fact: The international agreement to protect the ozone layer is the Montreal Protocol. It was signed in 1987 and aimed to reduce and phase out substances like CFCs that damage the ozone layer. This agreement is considered one of the most successful environmental treaties in history. Because of it, the ozone layer is slowly recovering.
Question 2: What does the ozone layer primarily protect us from?
- Infrared radiation
- Ultraviolet rays
- Radioactive waves
Answer: Ultraviolet rays
Fact: The ozone layer mainly protects us from ultraviolet (UV) rays coming from the sun. These rays can be very harmful to humans, animals, and plants. Without the ozone layer, people would face higher risks of skin cancer, eye damage, and weaker immunity. It also helps protect crops and marine life by blocking most of the harmful UV radiation.
Question 3: What feature of Earth can be seen from 225 miles above that indicates light pollution?
- Natural auroras
- Urban light clusters
- Star formations
Answer: Urban light clusters
Fact: From about 225 miles above Earth, astronauts can clearly see urban light clusters at night. These bright patches show how much artificial light cities give off. This glow is an indicator of light pollution, as it blocks the natural darkness of the night sky. Unlike auroras or stars, these clusters are man-made and linked to human activity.
