The correct answer is A. 0-30o latitude.
The tropical easterlies are a prevailing wind that blows from the east in the tropics, between the equator and 30 degrees north and south latitude. They are caused by the Earth’s rotation and the difference in temperature between the equator and the poles. The air at the equator is warm and rises, while the air at the poles is cold and sinks. This creates a pressure difference that drives the tropical easterlies.
The tropical easterlies are a major factor in the Earth’s climate. They help to distribute heat around the globe and they also play a role in the formation of hurricanes and other tropical storms.
Option B is incorrect because the prevailing wind in the mid-latitudes is the westerlies. Option C is incorrect because the prevailing wind in the high latitudes is the polar easterlies. Option D is incorrect because it does not include the equator.
