A) Slow ascent of air\[\to \]slow condensation \[\to \] heavy downpour
B) Rapid ascent of air\[\to \]large raindrops\[\to \]heavy downpour
C) Pressure decreased\[\to \]air compressed\[\to \]heavy downpour
D) Descent of air\[\to \,\,\text{air}\]warmed\[\to \]heavy downpour
Correct Answer: C
Solution :
There is negative relationship between rainfall and pressure. When the air pressure is lower, more rainfall occurs. When there is low pressure in the atmosphere, the air bubbles that is rising, are always hotter than the air around. If the ground is heated then air will rise. The cool air will produce condensation that will ultimately lead to rainfall.
