← GeographyWhich effect arises when the Coriolis force deflects atmospheric pressure gradients near the poles?
A)Geostrophic winds flowing parallel isobars✓
B)Hadley cell formation promoting equatorial heating
C)Ekman spiral formation influencing ocean currents
D)Rossby waves amplification reducing temperature gradients
💡 Explanation
When pressure gradients exist and the Coriolis force deflects air masses near the poles, the resulting pressure gradient force balances the Coriolis force, creating geostrophic winds flowing along isobars. Therefore geostrophic balance occurs, rather than Hadley cells, Ekman spirals, or Rossby wave amplification, which depend on different latitudinal and oceanographic processes.
