Air circulation is caused or affected by several factors, including: 1) Convection currents caused by differences in radiant heating between equatorial and polar regions (option A) 2) Mountain ranges that can influence air flow and create local wind patterns (option B) 3) The rotation of the Earth on its axis, which leads to the Coriolis effect and the formation of large-scale wind patterns like trade winds and jet streams (option C) All of these factors play a significant role in determining global and local air circulation patterns, which is why D) All of the above is the correct answer.
