Orographic lifting occurs where sloping terrains, such as mountains, act as barriers to the flow of air. a) true
b) false

a) true

Explanation:

Orographic lift is one of the processes that induces precipitation. It occurs when a moving air mass is forced from a low elevation to a higher elevation as it encounters a sloping terrain such as a mountain. This increase in elevation causes the air mass to cool rapidly adiabatically with a relative humidity that might be up to 100%. The cooling effect leads to condensation of water molecules in the air mass, which then fall as precipitation.
