ANSWERS
Question 1 : Answer: B – Light pollution is the excessive or misdirected artificial light that affects the natural environment and limits our view of the stars.
Question 2 : Answer: C – Noise pollution is a different kind of environmental pollution. Light pollution types include glare, over illumination, skyglow, and light trespass.
Question 3 : Answer: B – Artificial light brightens the night sky, creating a “skyglow” that can block out starlight and make it harder to see stars.
Question 4 : Answer: B – Light pollution disrupts natural behaviors, especially in nocturnal animals. It can affect migration, reproduction, and even survival by interfering with natural light cues.
Question 5 : Answer: A – Using outdoor lights only when needed and pointing them downward minimizes unnecessary light spill and reduces light pollution.
Question 6 : Answer: True – Blue and white lights scatter more in the atmosphere, contributing significantly to skyglow. Warmer lights are better for reducing light pollution.
Question 7 : Answer: A – A Dark Sky Reserve is a protected area with controlled lighting to reduce light pollution, offering excellent star visibility.
Question 8 : Answer: D – Dimming or reducing lights at night can save energy, reduce light pollution, benefit wildlife, and improve human health by promoting natural circadian rhythms.
Question 9 : Answer: B – Skyglow is the brightening of the night sky over populated areas due to artificial lighting reflecting off particles in the atmosphere.
Question 10 : Answer: D – Communities can reduce light pollution by using shielded lights, motion sensors, timers, and adopting policies to control excessive lighting.
Bonus Question : Answer: B – In a Dark Sky area with minimal light pollution, you can see thousands of stars, the Milky Way, and sometimes even other galaxies with the naked eye!
Total Your Score:
1-3: You’re a Night Light Novice! Time to learn more about the wonders of the dark sky.
