Understanding Air Transport: Advection vs. Convection
The question asks to identify the terms describing the horizontal and vertical movement of air.
- Advection refers specifically to the horizontal transport of air (or any fluid property like heat or humidity) from one location to another. This is typically associated with wind.
- Convection refers to the vertical transport of air, usually driven by differences in temperature and density. Warm air rises, and cooler air sinks, creating vertical currents.
Therefore, filling the blanks:
Advection refers to the horizontal transport of air while convection is the vertical transport of air.
This corresponds to Option A.
