because of the earths rotation and revolution.
As the Earth rotates, different locations of the world are either in sunlight or darkness. For this reason, different time zones have been created.
This is because of the earths rotation. Sunrise and sunset occur at different times in different places
Time zones are related to the earths rotation because the sun hits the earth at different times thus making the sun set and rise and the same time Ex: Chicago and Denver Colorado have different time zones but if the sun sets at 7:00 in Chicago you want it to be at the same time (7:00) in Denver. Even though we know that the sun cant hit the whole world with the same amount of energy at the same time.
The time of day is due to the earths rotation. Rotation is the number of times the earth revolves around itself.
There are 24 different time zones. Each time zone represent the hours of the day (because there are 24 hours in a day). This is because of the earths rotation.
The simple way to think of time zones is that there are 24 evenly spaced zones for the 24 hours of the day, during which the Earth rotates once. It's all about the hours though, not the rotation.
Each planet has its own time zones which are related to the speed of rotation of that planet. The times zones of the planet Mars are of only theoretical interest since no one actually lives there, but they are in any event not related to those of Earth.
It is necessary for the whole world because of the Earths orbit around the Sun and the rotation of the Earth itself. It is nighttime in New York before it is nighttime in California.
Earths rotation has been known to have had various effects on the Earth over time due to the velocity of its spinning, it has effected such things as:The shape of the Earth.The depths and currents of the Earths oceans.The Earths climate.And the tectonic forces on Earth.
Earth's rotation is slowing slightly with time; thus, a day was shorter in the past. This is due to the tidal effects the Moon has on Earth's rotation.

beacuse of the earths rotation
Its gravity is slowing the Earth's rotation, but the effect is small. Over a long time, though, the effect is significant.
The time of year is due to earth's revolution around the sun.
well if ur talking about water zones then 3 witch are twilight zone midnight zone and light zone
No. Days would be shorter; time itself would hardly be affected.
The time zones them self were assigned to avoid train crashes. Before, trains would be running on unestablished times, and when it came to sharing tracks, there were issues not knowing what time trains would be on.
The earth rotates on its axis once every twenty-four hours. It rotates toward the east, which is why eastern time zones experience sun rise before western time zones.
because the earth rotates
Earth's surface is divided into 360 degrees of longitude: 180 degrees east west of the Prime Meridian. Since Earth rotates at a steady rate on about 24 hours, its 24 standard time zones are centered the same number of degrees of longitude apart.The number is 15.
I have placed a link in the related links below.
every 15 degrees is a different time zone.
Jupiter. It rotates in just under 10 hours (Earth time).
