Parallels and Meridians
The Earth's surface is mapped using an imaginary grid system of paralleli e meridiani mappa that helps locate any point precisely.
Vocabulary: Cosa sono i meridiani - Meridians are imaginary circles passing through both North and South poles, with the Greenwich Meridian serving as the primary reference line.
Definition: Quanti sono i meridiani - There are 360 meridians in total, with 180 East and 180 West of Greenwich.
Example: Paralleli e meridiani scuola primaria - Parallels are circles parallel to the Equator, never intersecting each other. The Equator is the largest parallel, dividing Earth into Northern and Southern hemispheres.
Important reference lines include:
- Arctic Polar Circle
- Tropic of Cancer
- Equator
- Tropic of Capricorn
- Antarctic Polar Circle
Highlight: The combination of meridians and parallels creates the geographic grid system (reticolato geografico), essential for modern navigation and mapping.
