← GeographyOn an exoplanet rotating twice as fast as Earth, which outcome would result from changed Hadley cell dynamics?
A)Equatorial jet stream velocity increases modestly
B)More stable high altitude cloud formations
C)Subtropical desert belts widen significantly✓
D)Polar vortex patterns show decreased intensity
💡 Explanation
Hadley cell size shrinks due to increased Coriolis force causing atmospheric deflection (deflection increases if the planet rotates faster), therefore deserts widen, rather than jet streams intensifying because the gradient overall changes more significantly equatorially.
