Lines of latitude in length with increasing distance from the equator.

Lines of latitude decrease in length with increasing distance from the equator.

Explanation:

Latitudes are those distinct equidistant parallel lines encircling the Earth that start from the equator and advance towards the poles in both the northern and the southern hemispheres. As the cut-sectional diameter of Earth starting from the equator as circumference goes on decreasing towards the poles, the lengths of the imaginary latitudes encircling the Earth also go on decreasing gradually.
