Final answer:
Cold air masses do not tend to flow towards the equator.
Step-by-step explanation:
No, cold air masses do not tend to flow towards the equator. Air masses, including cold air masses, are generally driven by pressure gradients and the prevailing winds. In the Northern Hemisphere, cold air masses are more likely to flow towards the poles or move eastward due to the prevailing westerlies. Similarly, in the Southern Hemisphere, cold air masses tend to move towards the South Pole or eastward due to the prevailing westerlies. The movement of air masses is also influenced by other factors such as the Coriolis effect and the presence of high and low-pressure systems.
