Lines of latitude also called parallels to Equator.
<u>Explanation:</u>
Latitude helps to measure the degree of the earth from north to south. It is divided the earth through 180 imaginary lines ( in the form of a ring) in the direction east to west. These among those 5 imaginary lines were major lines that mark the center and extreme most degrees.
Keeping the Equator as the center holding 0 degrees and the two poles (north and south) holding 90 degrees. Each latitudes lines is called parallels. Each line measures one degree parallel to the Equator between the poles.
His results gave the first evidence that atoms were made of smaller particles. Specially, he proved the existence of negatively charged sub-atomic particles known as electrons.
