Question 962

How do air currents flow?
Air typically rises near sources of heat and descends elsewhere. Since air doesn't normally accumulate in one place and leave another place empty, it tends to form circulating currents. The air rises near hot objects, flows outward above those objects, cools and descends, and finally flows back toward the hot objects from beneath them. These circulating currents are called convection cycles.
