Why the Earth's surface is divided into time zones?

Answer 1

To co-ordinate human activity with time of day. A few decades ago it was important for people to consider noon as corresponding with the maximum height of the sun. Tradition maybe. Actually it doesn't really matter what time stamp you put on the phase of the day and people could equally well work with a global time standard. They would just have to get use to talking about twelve o'clock noon before the sun comes up.

Answer 2

earth has multiple time zones because the sun is pointing at one side of the earth and if everybody had the same time zone the will go crazy because say its 2:00 and since the earth is pointing at us on th other side it ill be dark but its 2:00.

Answer 3

We have different time zones because the suns light shines on different parts of the earth so when we get light the other half of Earth is dark, so this makes us in the day and another part at night. There are other angles that it hits so a side gets light to.

Answer 4

It is split into time zones because as the Earth rotates, different places or "zones" face the sun at different times thus we have "Time Zones"
