Longitude is the angular distance of a place east or west of the Greenwich meridian, or west of the standard meridian of a celestial object, usually expressed in degrees and minutes.
The Polynesians developed the fine art of navigation by stars, inherited from the early arab navigators. Arabians used hand measures to measure the height of the star above the horizon to determine their latitude according to the angle determined.
Hi Moran
I don't think there is a big different at all but what I know is that Norway is colder and has more rain.
Another different is because Spain is closer to the equator but Norway is closer to the arctic.
I hope that's help ! Have a nice day :)
