Answer:
Denser air flows in to replace rising air
Explanation:
Movement of air caused by temperature or pressure differences is wind. In fact, the air moving from high to low pressure follows a spiralling route, outwards from high pressure and inwards towards low pressure. Change in air pressure at a given locality often indicates a change. Both air pressure and air density decrease rapidly with increasing altitude.
The denser air flows into the area of low pressure to replace the rising air. This creates a huge convection cell called a Hadley Cell, named after George Hadley
