← GeographyWhich outcome occurs when increased surface heating disrupts Hadley cells?
A)Expansion of subtropical desert regions✓
B)Diminished strength of polar jet
C)Increased frequency of La Niña events
D)Weakening of deep ocean layering
💡 Explanation
A weakening of Hadley cells leads to changes in precipitation patterns as the Intertropical Convergence Zone shifts, because the atmospheric circulation is altered by **thermal forcing**, leading to expansion of subtropical desert regions; therefore drying increases, rather than changes in jet streams.
