Dennis Kushner, age 14'. of Fairview Pam., Ohio for s question:

What is the earth's diameter at the poles?

Through billions of years of good living, our old earth has put on a little bulge around the waist. The globe is a little wider at the equator. Its diameter at the equator is a little longer than its diameter through the two poles. The difference, however, is so slight that on a twelve inch globe it amounts to only the tiniest fraction of an inch. Hence, a model globe of the earth does not show the slight, middle aged spread at the earths waistline.

Keep in mind as a rough estimate that the world is about 25,000 miles around the equator and about 8000 miles through the middle. The diameter through the equator is somewhat more than 7926 miles. The diameter through the poles is almost 7900 miles. The difference is about 26 1/2 miles.
