Question

Accepted Answer

The transfer of heat through horizontal movement of air is called Advection.

Here's why:

*   **Advection:** Advection is specifically defined as the horizontal transport of heat or other atmospheric properties (like moisture) by the wind. Think of a warm air mass moving horizontally into a colder region, warming it up. This is a direct example of heat transfer via advection.

Here's why the other options are incorrect:

*   **Convection:** Convection involves vertical movement of air (or any fluid). Warm air rises, and cool air sinks, creating a vertical circulation pattern. While convection *can* contribute to heat transfer, it's primarily a vertical process, not horizontal.

*   **Diffusion:** Diffusion is the process of molecules spreading out from an area of high concentration to an area of low concentration. While diffusion does play a role in heat transfer at a molecular level, it's not the primary mechanism for heat transfer through the *movement of air* on a larger scale. It's a much slower process than advection.

*   **Albedo:** Albedo is the measure of how much solar radiation a surface reflects. It doesn't describe a process of heat transfer. A surface with high albedo reflects a lot of sunlight (and therefore absorbs less heat), while a surface with low albedo absorbs more sunlight (and therefore more heat). It's related to the *absorption* and *reflection* of heat, not the *transfer* of heat via air movement.
