They do follow the longitude approximately but in some regions there are political reasons for changing them, for example a large part of Russia is on GMT+3 to make things simpler for the people who live there.

Do the time zones always follow the lines of longitude?

yes


Why most time zones follow the prime meridian not the lines of longitude?

The prime meridian is a line of longitude


Which way to time zones run?

Time zones are based off of longitude


Is time zones longitude or latitude?

Time zones are primarily based on longitude rather than latitude. The Earth is divided into 24 longitudinal sections, each representing one hour of time difference. This allows for a standardized way to coordinate time across the globe.


Are latitude lines used to determine time zones?

It's the lines of longitude which are used to define time zones, not lattitude.


How are time zones broken up according to longitude?

There are 24 hours in a day and 360 degrees so the globe is divided into 24 time zones that are 360°/24 = 15 ° wide. Of course the time zones do not follow the longitudes exactly. Different localities may opt to be part of an adjacent time zone for business purposes. Most of western Europe is on the same time zone even though the countries span about 30° of longitude. There are also some locations that choose to follow their own time zone that is half way in between the nearest time zones - such as India and central Australia. The "international date line" follows (roughly) the 180 ° longitude.


What global grid lines determine times zones?

The Prime Meridian (0 degrees longitude) and the International Date Line (180 degrees longitude) determine time zones across the globe. Time zones are typically one hour apart for every 15 degrees of longitude difference.


Is latitude the basis for establishing time zones?

Time Zones are based on lines of Longitude - with detours to avoid land.


How are the time zones divided up?

Time zones are divided based on lines of longitude, with each time zone roughly covering 15 degrees of longitude. There are a total of 24 time zones around the world, each one hour apart from the next, although some countries may use half or quarter-hour offsets from standard time zones. The Prime Meridian (0 degrees longitude) in Greenwich, England is the starting point for the time zone calculations.


The longitude of location determines which time zones are the result of?

earth's rotation


Why don't time zones exactly follow lines of longitude?

In order to avoid splitting a state, county, city, or town with a time-zone boundary. Can you imagine how you might handle your work schedule, dental appointments, bus schedule, or the TV prime-time lineup, if your city had two different time zones in it ?


Are time zones based on 35 degrees longitude?

No, time zones are based on 15 degrees longitude, because there are 360 degrees of longitude on the globe and 24 hours a day, so 360/24 makes 15. But, there are 24 time zones for 25 times (-12, -11, ... -1, 0, +1, ... +11, +12) and half-hour and quarter-hour variations so it really isn't based on anything.
