Question

The length of a parallel increases as we move away from the poles towards the equator. Why ?

Answer 1

As you know the earth is circular in shape. The biggest circumference is at the equator because diameter is the longest straight line on the circle. But as we move away from equator the circumference keeps on decreasing. That is the reason, the length of a parallel increases as we move away from the poles towards the equator.

Hope this clears your doubt.

Answer 2

Hey buddy!!!
As you can see in the image above, the parallel lines are longer at the equator and shorter towards poles.
This is because these line run east–west as circles parallel to the equator & are known as latitudes.
