Why does air flow ?

1.	Why does air flow ?
Answer» The movement of air across the earth determines the weather and climate of all regions. The sun’s radiation heats up the land, sea and the air. The land and water bodies also heat up the air, making it less dense. Here, hot air increases and creates a low pressure over that area and cold air sinks and creates a region of high pressure. Air, like all fluids, likes to maintain equal pressure. To do so, cold air from high-pressure areas flows into regions of lower pressure. The primary cause of airflow is the existence of air. Air behaves in a fluid manner, meaning particles naturally flow from areas of higher pressure to those where the pressure is lower. Atmospheric air pressure is directly related to altitude, temperature, and composition.
