Which phenomenon causes surface winds to deflect westward relative to pressure gradient within Hadley cells?

💡 Explanation

When surface winds move towards the equator within Hadley cells, the Coriolis effect deflects their path westward because Earth's rotation affects moving objects, changing their trajectory from a straight line. Therefore the Coriolis effect explains the deflection, rather than thermal expansion, mixing, or latent heat, which involve differing atmospheric processes.
