Which of the following is true with reference to 180° E and 180°W longitude?

Correct option is B

The 180° E and 180° W longitudes are the same line, referred to as the Antimeridian. This line plays
a vital role in separating the Eastern and Western Hemispheres. It is a conceptual boundary
used in global navigation and timekeeping. Additionally, the International Date Line (IDL) closely
follows this meridian but deviates to avoid splitting countries into different calendar days. The IDL
ensures smooth functioning of time zones and global communication by marking where the new day
begins or ends.
Information Booster:
· Antimeridian: Another name for 180° longitude, marking the transition between Eastern and Western
· Hemispheres.
· International Date Line: Follows the 180° meridian but zigzags to accommodate political and Geographic boundaries.
· Crossing the line eastward subtracts a day, while crossing westward adds a day.
· Key for maintaining the continuity of time zones and calendar dates globally.
Additional Knowledge:
· Opposite to each other: Opposite to 0° longitude but the same for 180°.
· 180° apart: They are not separate but represent the same line.
· Distance remains constant: This line is a conceptual boundary without physical distance implications.
