|
Answer» The scientists studied Earth's movements after which they came up with 24 time zones which are theoretically drawn on the world map. A time zone is a region of the globe that observes a uniform standard time for legal, commercial, and social purposes. Time zones tend to follow the boundaries of countries and their subdivisions because it is convenient for areas in close commercial or other communication to keep the same time. |
