Atmospheric circulation on large scales is driven by: (select one)

a. the coriolis effect

b. mid latitude deserts

c. the hadley and polar cells

d. the equator-pole energy imbalance

Atmospheric circulation on large scales is driven by c. The Hadley and Polar cells

Explanation:

These are the pressure-wind belts found on the earth's surface and are in direct relation to the Coriolis force of the earth which deflect the winds in the northern and southern hemispheres, based on earth rotation of the axis. On a large scale the atmospheric circulation of earth is in the command if the Hadley cells that originate over the tropics under the impact of the sun rays and  with due convective activity gets heated upward and reaches the poles and hence he poles have a polar cell which reaches downward the topics and reduced the temperature of the tropics. Thus the general circulation of the atmosphere id dependent on these cells and the impact they have on the earth's surface features.  These winds and pressure belts set the stage for the all-weather phenomenon on earth.
