Answer 2

Answer:

In the equatorial region, there is 4 ‘O clock rain because, the vertical rays coming from the sun heat up the land at a huge extent. Due to this, the formation of water vapour takes place. The water vapour gets accumulated in the upper layer of the atmosphere and come down in the form of rain. Due to this reason, there is 4'o clock rain in equatorial region.
