Q. The vertical movement of air is known as__:
Answer: air current
Notes: An updraught or downdraught is the vertical movement of air as a weather related phenomenon. Better known as air current, they can be caused by differences in temperature, pressure, or impurity concentration. Temperature differences can cause air currents because warmer air is less dense than cooler air, causing the warmer air to appear "lighter." Rising air is associated with turbulence as it creates a low pressure on the surface.
