Question

the main mode of heat transfer that is directly responsible for creating wind is...
a reflection.
b radiation.
c convection.
d conduction.
e refraction.
f conversion.

Explanation:

Wind forms due to differences in air temperature (and density) caused by heat transfer. Convection is heat transfer via fluid (air) movement. When air is heated, it rises (less dense), and cooler air moves in, creating wind. Reflection (A), Radiation (B, heat via EM waves), Conduction (D, heat through direct contact), Refraction (E, light bending), and Conversion (F, energy change) don’t directly create wind.

Answer:

C. Convection.
