With respect to the three main lifting (cooling)mechanisms (local heating,orographic,and frontal),which of the following is correct?
A)the greatest average annual rainfall on Earth is due to local heating and frontal activity.
B)a single convectional storm triggered by local heating affects large geographical regions.
C)all three mechanisms do not occur within North America.
D)given the necessary physical requirements,orographic precipitation is usually the most consistent type of the three.
E)given the necessary physical requirements,frontal precipitation is usually the most consistent type of the three.

Given the necessary physical requirements, orographic precipitation is usually the most consistent of the three main lifting mechanisms. This is because mountain ranges provide a constant barrier to the prevailing winds, forcing upward movement of moist air and subsequent cooling and precipitation on the windward side. Local heating and frontal activity are more variable in terms of their occurrence and intensity. A and B are incorrect because while local heating and frontal activity can contribute to high rainfall in certain regions, they are not the main mechanisms responsible for the greatest average annual rainfall on Earth. C is incorrect because all three mechanisms do occur within North America.
