Answer:
a) true
Step-by-step 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.
