Question 10
Which statement describes the greenhouse effect? (1 point)
a. Glass buildings reflect sunlight into the atmosphere and increase its temperature.
b. We live in a greenhouse-like environment: sunlight reaches Earth's surface, but heat is reflected back to Earth by a CO₂ layer in the atmosphere.
c. Glass absorbs heat poorly, increasing atmospheric temperature.
d. Broken CO₂ and ozone layers remove the barrier to sunlight, increasing air temperature.
e. Vehicle-engine smoke is a heat source at Earth's surface; it enters the atmosphere and causes global warming.
