How many latitudes are?

Answer 1

The angle between the north pole and the south pole defines 180 degrees of latitude.

The number of different latitudes there are is the same as the number of different lengths

there are on a ruler, and the number of different amounts of water there can be in a jug.

Even if the ruler or the jug have some marks on them, there are numbers between the marks.

The latitude in the center of your kitchen, the one in the center of your garage,

and the one in the center of your backyard are all different latitudes.

In fact ... If you put your hand down flat on your desk with your fingers pointing east,

then each finger is at a different latitude ! (And so is each space between the fingers.)
