Zero.
They are the axes of the coordinate system that is used for places on the earth's surface. Every point on the earth's surface is a certain number of degrees east or west of the prime meridian (its longitude) and a certain number of degrees north or south of the equator (its latitude).
At the equator, you will see no circumpolar stars.
Yes. The equator is defined as the 'zero' of latitude. For every latitude number, there's one of them north of the equator and another one with the same number south of the equator. In order to be clear about which one you mean, you have to mention the label 'north' or 'south' along with the number.
-- Pick any number between zero and 90. -- That number north latitude and that same number south latitude are equal distances from the equator.
yes, you just even used it in a question. like the equator is.....
"Equator" is a common noun because it is a general term used to refer to a specific geographical feature.
It's not "used" for anything.
yeah!
latitude
90 degrees north of the equator, and 90 degrees south of the equator. Total: 180 degrees, from pole to pole.
Latitude is the measurement used to determine the distance of a place from the equator. It is expressed in degrees north or south of the equator, ranging from 0° at the equator to 90° at the poles.
The lines used to measure distances north and south of the equator are latitude lines. They include the equator (0 degrees latitude) and equidistant circles between the equator and the poles. Latitude lines represent the surface points having the same angle from the equator, and planes perpendicular to the Earth's north-south axis.
