What happens to the length of a degree of longitude as one nears the North and South Poles? What happens to a degree of latitude between the equator and the poles?
distance between adjacent degrees of longitude decreases away from the equator because the meridians converge at the poles. With the exception of a few Alaskan islands, all places in North and South America are in the area of west longitude; with the exception of a portion of the Chukchi Peninsula of Siberia, all places in Asia and Australia have east longitude. Lat-The polar circumference of the earth is 24,899 miles; thus, the distance between degrees of latitude equals 24,899 ÷ 360, or about 111 kilometers (69 mi). If the earth were a perfect sphere, all degrees of latitude would be equally long. Due to the slight flattening of the earth in polar regions, however, degrees of latitude are slightly longer near the poles
