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

AI Explanation
The correct answer is B) topographic lifting. Topographic lifting occurs when air is forced to rise over mountainous or hilly terrain. As the air moves up the slope, it expands and cools, which can lead to the formation of clouds and precipitation. This is a common mechanism for generating lift in mountainous regions. The other options are incorrect because: A) Vertical lifting refers to convection, where air rises due to surface heating. C) Advective lifting occurs when warm air moves over cooler air, causing the warmer air to rise. D) Convective lifting is the same as vertical lifting, driven by surface heating.
