* Latitude lines are circles: A line of latitude, like 20 degrees north, circles the entire globe.
* Many countries span latitudes: Countries often extend across multiple latitude lines.
To find a specific country, you need both latitude and longitude.
For example, if you told me you were looking for a nation at 20 degrees north and 80 degrees west, I could tell you that's in the Caribbean Sea and could be part of the Dominican Republic, Haiti, or Cuba.
