Question

why do we have the concpet of time zone ?​

Answer 1

Answer:

Explanation:

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.

Hence, scientists made different time zones according to the earth's rotation with respect to the sun. The earth makes one full 360 degrees rotation in 24 hours. This means in one hour, the earth moves by 15 degrees. Using this information, scientist divided the planet into 24 sections or time zones.
