Which term describes vertical transport of heat and humidity?

Which term describes vertical transport of heat and humidity?

• A. Advection
• B. Convection
• C. Stable
• D. Unstable

Answer: (B)

Vertical transport of heat and humidity is caused by convection. In the atmosphere, warm, buoyant air rises, carrying heat and water vapor upward, while cooler air sinks to replace it. This vertical movement underlies many cloud formations and thunderstorm development. Advection refers to horizontal movement of air and its properties, not the vertical transport. Stable vs unstable describe the tendency of the atmosphere to resist or enhance vertical motion, but they’re about the likelihood of vertical movement rather than the transport mechanism itself.
