How do lines of latitude vary in length with distance from the equator? A. Lines of latitude don't vary systematically in length with increasing distance from the equator. B. Lines of latitude decrease in length with increasing distance from the equator. C. Lines of latitude remain the same length with increasing distance from the equator. D. Lines of latitude increase in length with increasing distance from the equator. Reset Selection

Option (B)

Explanation:

Latitudes are the lines that are parallel to one another and that runs in the east-west direction. The earth bulges at the equator, so the length of the latitude at the equator is the longest. This latitude, along with the longitude, gives the exact co-ordinate on earth.

These lines of latitude are extended in both the northern and the southern hemisphere, at a fixed interval of 10°. This ranges from 0° at the equator to the 90° at the poles. The length of these lines of latitude decreases with the increasing distance from the equator.

Thus, the correct answer is option (B).
