thanks!

You're welcome.

Well, yes:

Coriolis effect is really just conservation of angular momentum though. I do not think of it as a defection force but merely a continuation of its motion over a spinning earth.
One way to look at it is that if air rises over the hot equator, new air comes in from the North in the northern hemisphere to replace it. However the earth is spinning toward the East (sunrise) and as the radius from the spin axis is less in the far north than at the equator, that air is not moving as fast east as the earth is as it approaches the equator. Therefore it is left behind, to the west, of an observer near the equator and looks like a steady wind from the East, a trade wind if you will.
By the way you can figure out why hurricane winds are counterclockwise around a low pressure in the Northern hemisphere the same way.

Thanks again...

You are welcome :)

To determine the correct answer, let's break down the question and eliminate any incorrect options.

The question asks about the movement of winds in global circulation and their deflection by the Coriolis effect. The Coriolis effect is a result of the rotation of the Earth causing moving objects, like winds, to be deflected.

Now let's evaluate each option:

A. Westerlies: The westerlies are prevailing winds that blow from west to east. They occur in the middle latitudes, around 30-60 degrees latitude, both in the Northern and Southern Hemispheres. However, they do not move toward the equator, so this option can be eliminated.

B. Trade winds: The trade winds are prevailing winds that blow from the subtropical high-pressure belts toward the equator. They are located between 30 degrees latitude and the equator in both the Northern and Southern Hemispheres. Trade winds are indeed deflected by the Coriolis effect, so your answer of B is correct.

C. Polar easterlies: The polar easterlies are cold prevailing winds that blow from the polar high-pressure belts towards low-pressure areas at around 60 degrees latitude. They do not move toward the equator, so this option can be eliminated.

D. Subtropic winds: There is no specific wind called "subtropic winds." Therefore, this option is incorrect.

Based on the evaluation, it is clear that the correct answer is B. The trade winds move toward the equator and are deflected by the Coriolis effect.
