Polar maps usually put the named pole at the center of the map.
A polar projection of the earth shows a pole (north or south, depending on the projection) at the center of a circular map. The equator is the circumference of the circle.
Polar projections are often made in what is called the Azimuthal Equidistant Projection. The projection would be made tangent at the north pole, or at the south pole. These projections allow you to make linear measurements from the pole to any point on earth. These measurements are the shortest distances from the pole to the points and can be directly compared to one another. A polar projection shows the poles; I learned it in my science class.
The south polar region's elevation is higher than the north polar region, because the south polar region is a continent and the north polar region is ocean.

Polar air masses form north of 50 degrees north latitude and south of 50 degrees south latitude. These air masses are characterized by their relatively cooler temperatures compared to tropical air masses.

A polar projection map projects the poles. This type of map displays the Earth's surface with the North or South pole at the center, and lines of longitude converging at the pole. This type of map is useful for showing polar regions accurately.
Those are the polar zones.
