Concept:Convectional rainfall forms when intense surface heating makes moist air rise rapidly, cool, and condense.
Explanation:The equatorial belt receives strong, direct sunlight all year.
This constant heating warms the air near the ground.
Warm, moist air becomes lighter and rises quickly.
As it ascends, the air expands, cools, and reaches its dew point.
Water vapour condenses to form cumulonimbus clouds, producing heavy afternoon downpours.
These showers are typical of equatorial climates, which have high temperatures and humidity daily.
Thus, convectional rain is closely associated with equatorial areas.
Answer:D. equatorial areas
