Question

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

Answer 1

Answer:

circles radius increase

Explanation:

Earth is sphere

Sphere can be thought of a collection of parallel circles. these circles radius increase as we move towards center from a point on sphere.

Answer 2

Answer:

Earth is perceived as a round spherical body. So as we know, a sphere has a diameter, the longest chord diving the circle in two halves.

And any other parallel lines or chords gets smaller towards the pole as it joins two sides.

Therefore, assuming equator as the longest chord or diameter, the length of the parallel lines increases more towards equator than in poles.
