Two students designed an experiment to study the effect of solar radiations on four cities of Earth. They used a globe to represent Earth and a light bulb to represent the sun. The four cities were labeled A, B, C, and D on the globe at the latitudes shown in the chart below. City Latitude A 33° 53' S B 64° 03' N C 39° 56' N D 2° 09' S The students moved the globe slowly around the light bulb in an elliptical orbit. Based on the experiment, the students are most likely to conclude that the least variation in seasons will be experienced at City A City B City C City D

Great experiment! Everybody should try it if they can get the equipment.

It demonstrates a lot of things that are very hard to explain in words.

I hope the students remembered to tilt the axis of the globe. If they didn't,

and instead kept it straight up and down, then each city had pretty much

the same amount of bulb-light all the way around, and there were no seasons.

If the axis of the globe was tilted, then City-D had the least variation in

seasons. City-D is only 2° from the equator, so the sun is more direct

there all year around than it is at any of the others.
