How many degrees are there per line of longitude and latitude?

Lines of latitude and longitude intersect, creating a grid that allows anyone in any location to pinpoint a geographic location. There are 360 degrees of longitude (because meridians make Great Circles around the globe), and there are 180 degrees of latitude.

How is a degree of longitude or latitude further subdivided?

Degrees of latitude and longitude can be further subdivided into minutes and seconds: there are 60 minutes (‘) per degree, and 60 seconds (“) per minute. For example, a coordinate might be written 65° 32’ 15”. … A degree of longitude varies in size.

What is the climate like at 90 degrees south latitude?

The geographic South Pole is located at 90 degrees south latitude. The station accommodates up to 250 people during the austral summer. Temperatures there average minus 60 degrees Fahrenheit year-round.

Which latitude line is at 0 degrees?
