Mechanical lifting of air by the upslope slant of the terrain is called __________.

Correct Answer: Option B — topographic lifting

Topographic lifting, or orographic lifting, occurs when an air mass is forced upward by terrain features like mountains or cliffs. As the air rises, it cools adiabatically, which can lead to condensation and the formation of clouds or fog, a common meteorological phenomenon described in standard maritime weather texts.
