Question

A game of reading the meridians on the world map is going on. Shaheen and Sanket are asking each-other to locate places on specific meridians and are making notes of the same. Shaheen asks Sanket to locate Wrangel Island on 180° meridian. Sanket could locate the island in the map but both are confused while making a note of it. They are puzzled whether to write 180°E or 180°W? What would be the precise answer? Please help them. Can we use a similar logic with reference to 0° meridian as well? 

Answer 1

The earth is circled by the 0° and 180° meridians, which are opposed to one another. The eastern and western hemispheres of the globe are separated by this circle. The Wrangled island can be written to be located on a 180° meridian by Shaheen and Sanket.
