The three mechanisms cause air to rise are orographic lifting, frontal wedging, and convection-convergence.

Question

Quizplus · Accepted Answer

This statement is true. Orographic lifting occurs when air is forced to rise over a mountain or other elevated topography. Frontal wedging occurs when two air masses of different temperatures meet, with the cooler air mass undercutting and lifting the warmer air mass. Convection-convergence occurs when two air masses of equal temperature converge and are forced to rise due to their inability to occupy the same space.
