Around Earth Day and whenever the homepage features rainforests, reefs or renewable energy, Bing runs environment-themed questions. They stay factual and general-interest, covering climate, ecosystems, recycling and conservation, and they're easy to verify once you know what's being asked.

The themes that repeat
Expect questions on ecosystems and biodiversity, which rainforest is the largest (the Amazon), which reef is the biggest (the Great Barrier Reef, off Australia), renewable energy sources like solar, wind and hydro, recycling and plastics, and climate basics such as which gases trap heat.
Earth Day questions
Earth Day, April 22, brings its own mini-set: it began in 1970 in the United States, and questions often ask its date, origin year, or annual theme. If the homepage image is Earth from space or a conservation scene in late April, expect this angle.
Example questions
Bing has asked which gas plants absorb (carbon dioxide), what the largest tropical rainforest is (the Amazon, mostly in Brazil), and which energy sources count as renewable (solar, wind, hydro, geothermal, biomass). Superlatives like 'largest' or 'most' deserve a quick check because rankings depend on how they're measured.
Verifying quickly
Search the specific subject plus the fact, 'largest coral reef' or 'Earth Day year started', and prefer scientific or official sources for anything numerical. The caption usually names the ecosystem or species in the day's photo, which is your starting point.
