← GeographyWhich convection outcome results from increased atmospheric CO₂?
A)Hadley cell expansion towards poles✓
B)Reduced tropospheric temperature gradients
C)Declining latent heat ocean transfer
D)Contraction of subtropical arid zones
💡 Explanation
Hadley cell expansion occurs due to increased atmospheric CO₂, driving intensified warming at the equator, which enhances the convection cycle. This forces poleward expansion because excess energy migrates outwards, therefore expanding the cell rather than reducing temperature gradients.
