Final answer:
The step that is not part of a normal convection cycle is when air flows from a high-pressure area to a low-pressure area.
Step-by-step explanation:
The step that is not part of a normal convection cycle is option B: Air flows from a high-pressure area to a low-pressure area. In convection, heated air rises due to its lower density, and then cooler air sinks towards the surface. This creates a cycle of heat transfer. Additionally, unequal heating creates a pressure difference, driving the flow of air.
