Identify two major reasons for the movement of the global air masses.

Answer 1

1. Temperature differences: The primary reason for the movement of global air masses is differences in temperature. Air masses will move from areas of high pressure to areas of low pressure in an attempt to equalize the temperature differences. The unequal heating of the Earth's surface by the sun creates these temperature variations, driving the movement of air masses.

2. Earth's rotation: The Coriolis effect, caused by the Earth's rotation, also plays a significant role in the movement of global air masses. This effect causes the deflection of moving air masses to the right in the Northern Hemisphere and to the left in the Southern Hemisphere. The Coriolis effect influences the direction of air movement, leading to the creation of distinct wind patterns and the movement of air masses across the globe.
