Q1
In a coastal city, a clear night is followed by a calm, sunny morning. By 8 a.m., commuters notice a visible brown haze near the ground and poor air quality alerts. A weather balloon shows air at the surface is cooler than air about 300 m above it. Under normal conditions, air temperature decreases with altitude and warm surface air rises and mixes pollutants upward. Which statement best explains why pollution is worse this morning?
