Lines of what determine the time zone?

Answer 1

Greenwich outside London, Britain.

prime meridian

Greenwich Meridian

_____________

Clarification. Each of the world's basic time zones is 15 degrees of latitude wide. It should be obvious that 15 degrees times 24 equals 360 degrees, accounting for the entire globe. The system of latitude and longitude was established in Greenwich with Greenwich at zero degrees longitude, but the time zones were defined in such a way that Greenwich is in the middle of its zone. That time zone extends for 7.5 degrees to the east and to the west of the Greenwich meridian, defining its full 15 degrees.

Answer 2

Since each country determines its own time zone(s), most time zone boundaries are international borders. Countries base their time zones at least loosely on the longitudes they cover, with every fifteen degrees of longitude corresponding to one hour.

Answer 3

Time zones are determined by lines of longitude, specifically every 15 degrees of longitude represents one hour difference in time. The Prime Meridian at 0 degrees longitude sets the standard time zone (Greenwich Mean Time), with time zones moving eastward and westward from there. Countries or regions near each other typically share the same time zone for convenience.

Answer 4

The Prime Meridian that runs through Greenwich, England, is the base point for time zones.

Answer 5

lattitude determine the time zoes of different cities
