Which of these is not a major cause of global wind circulation?
(a) Inequalities in the distribution of solar radiation.
(b) Carbon dioxide concentration
(c) Position of the major Earth mountain ranges
(d) The coriolis Effect
Explanation
The correct answer is (b) Carbon dioxide concentration because global wind circulation is primarily driven by inequalities in solar radiation, the Coriolis effect, and the position of major mountain ranges. Uneven heating between the equator and poles creates pressure differences, driving wind movement, while Earth's rotation causes the Coriolis effect, which deflects winds and shapes global wind belts. Mountain ranges further influence regional wind patterns by acting as barriers, leading to precipitation on windward sides and dry conditions on leeward sides (orographic effect). While carbon dioxide affects climate change, it does not directly drive global wind circulation, making it the incorrect option.
