Question

Explain the time zone?How does the time in one country differ from the one in another?

Answer 1

Just like there are 24 hours in a day, there are 24 time zones.

Each zone is determined by the degree of longitude it is (it changes with every 15 degrees longitude east or west). As you go East, you GAIN an hour and  going WEST, you LOSE an hour--until a full day is either lost or gained.

    You can make a time zone line by making 25 marks on a sheet of paper (the 13th line would be 0 degrees). The first mark on either side of the 0 would be 15 degrees East/West, and continue numbering until you reach 180 degrees on either end (15,30, 45,60,75,90,105, 120, 135,150, 165, and 180--in other words), and this is called the INTERNATIONAL DATE LINE.  So, for example, if one town is located at 43 degrees longitude East and it's 6 p.m. and another town is at 137 degrees East, you would count the hours between the 45 and 135 marks (6 marks), you could figure out that it would thus be 12:00 midnight. (Note: you always count from the line closest to the actual longitude reading both ways). Going WEST, you'd lose those 6 hours, so it would be 12:00 noon.

     There are 4 time zones in the "Lower 48" states--East, Central, Mountain, and Pacific. When you add Alaska, there are 5 zones, and 6 when you add Hawaii.

    An example of time differences between countries is that I live in the Central US time zone, and my friend in England is 6 hours AHEAD of me (since it is about 4 p.m., on Sunday afternoon here, it is 10 p.m. in England), and my friend in Australia is 16 hours ahead of me, so it is 8 a.m. on Monday morning there).

    Your local telephone book should have a page at the beginning listing the countries with either a plus or minus sign and number (like +15), which tells you that country is 15 hours ahead of your time.

This site--http://www.worldtimezone.com--shows a World Time Zone Map with current time (12 hour format) or you can change Time mode: 12 hours (AM/PM) or 24 hours (military time), like I described above.

Answer 2

Do you have a globe that you can look at?  If not, use a ball or something round like an orange.

Take a lamp or a flash-light and turn it on and place it on a table where the light is shining toward the globe / ball / orange.

You will see that some of the globe is in the light and some is in the dark and if you slowly turn the globe you will see that the light and dark areas move.

This is what happened each day as the earth revolves - for part of the day we are in the area that is facing the light (the sun) and that is the hours of day-light and for other part of the day it is dark, which is night-time.

To make things easier we have divided the earth into 24 time zones that coincided with the 24 hours of each day.  

As the earth revolves and it gets light, it becomes, for example, 6am in New York, then an hour later it becomes 6 am in Chicago, then an hour later it is 6am in Denver, then an hour later in Los Angeles.
