Question

how are doldrums produced?
prevailing easterlies
prevailing westerlies
converging trade winds
diverging trade winds

Explanation:

Doldrums are regions near the equator where there is little to no wind. The trade winds from the Northern and Southern Hemispheres converge near the equator. This convergence causes the air to rise rather than move horizontally, resulting in calm conditions - the doldrums. Prevailing easterlies and westerlies are not directly related to the formation of doldrums. Diverging trade winds would not create the calm conditions characteristic of the doldrums.

Answer:

converging trade winds
