molecules T/F
,Answer: True
●● Aerosals are solid/liquid particles, at high concentrations they cause
haze T/F

Answer: The troposphere and mesosphere.
●● The tropopause...
Answer: is higher in altitude during summer than in winter
●● In an inversion layer, temperature decreases with height T/F
Answer: False
