Glossary term: Latitude
Description: La Terre est une sphère. Pour définir les lieux sur la Terre, deux séries de lignes imaginaires sont tracées sur la surface de la sphère : Les lignes de latitude sont des cercles qui font le tour de la Terre parallèlement à l'équateur. La latitude est mesurée par un angle. Ainsi, l'équateur a une latitude de 0 degré. Les latitudes de l'hémisphère nord sont positives, celles de l'hémisphère sud sont négatives. Les pôles Nord et Sud ont les latitudes les plus élevées en valeur absolue. Le pôle Nord se situe à +90 degrés et le pôle Sud à -90 degrés. Les pôles sont également traversés par des lignes qui décrivent de grands cercles, perpendiculaires à l'équateur. Ce sont les lignes de longitude.
