In the equatorial region, most rainfall results from?

In the equatorial region, most rainfall results from the conventional effect. The conventional effect occurs when the sun heats the earth's surface, causing warm air to rise and cool air to sink. As the warm air rises, it cools and condenses, forming clouds. These clouds then release their moisture as rainfall. In the equatorial region, the sun's rays are most intense, and the land and water surfaces are warm, causing warm air to rise and leading to the formation of abundant rainfall. Other factors such as humidity and wind patterns can also influence rainfall in the equatorial region. However, the conventional effect is the primary cause of rainfall in this region.
