Question

Why are there 360 longitudes and only 180 latitudes?

Answer 1

A circle is divided into 4 quarters of 90 degrees each.

Longitude lines pass through the north and south poles. If you stood above the earth and looked down on the north pole from above, you would see the complete circle of the equator. So longitude goes from zero to 360 degrees.

Latitude lines are parallel to the equator which has latitude = zero degrees.

Latitude measures how far away a location is from the equator in degrees. Since 30 degrees latitude doesn’tell you if the location is closer to the north or south pole, latitude is assigned a positive value toward the north pole and a negative value toward the south pole.

Each section from the equator to the pole is 90 degrees and the range from pole to pole is 2 quarters of a circle, or 180 degrees

Answer 2

Longitude lines are simply half-circles, therefore, if you align them out at 1° arc, then it turns to be  360 degrees. Latitude lines are comprehensive circles, with the middle at 0° and the pole at 90°. The South Pole and the North Pole have separated by 180° apart, The longitude lines cross from the North Pole to the South Pole.

While persisting on the North Pole, you can ideally recognize the whole circle of the globe.

This is why it begins at zero and finishes at 360 longitudes. Latitude lines are the range of a distinct place from the tropics. The Equator including the diameter of the earth commences from zero to 180.
