The Earth is a sphere. The sun's position appears different at different places on the planet.
Time zones are political and are set so that nearby (500 to a thousand miles away) places are all running at the same clock time.
Different time zones exist to account for the Earth's rotation, which causes parts of the world to experience daylight at different times. By dividing the Earth into different time zones, we can coordinate schedules and ensure that activities are conducted during appropriate times of the day – for example, work hours during daylight.

Some changes that can occur in the aquatic ecosystem as a result of nutrient loading is called algal bloom. This is where there is a rapid increase of growth of phytoplankton which causes dead zones. These dead zones consume too much oxygen where plants and sea life can no longer survive in these areas.
Earth's tilt
There are two reasons that there are wind zones on the Earth. One is the Coriolis Effect. The other is because there are sustained areas of high and low pressure on the Equator and on the poles.
There are forty times zones not five.
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.

you only need to change the plug on the adapter, to watch dvds you need to change it too european zones , i think it lets you change it three times
There are 24 times zones in a day, one for each hour.
The belts and zones of Jupiter result from the planet's convetion and it's rapid differential rotation.
water, wind and sun
because our country is so large
Zones out!
unknown
because from virgina to California you change time zones 5 times or 4
subduction zones, ex. maranas trench
