different time zones are needed to tell time
time zones are not completely straight because it could split cities or counties in half. on half of the city could be in one time zone and the other half could be in another time zone. so the person across the street from you could be in a different time zone.
no
Time zones are marked on a time zone map using a series of vertical lines that represent the boundaries between each time zone. Each line indicates a change in time by one hour, with some lines extending out into the ocean to encompass specific regions. The time zones are typically labeled with the offset from Coordinated Universal Time (UTC).
No line of longitude bends, but the time-zone boundaries are defined to depart from the meridians in order to accomplish that.
Sometimes a portion of a state's boundary will match the time zone.According to one online map, these 12 states have some portion of their borders with other states on a time zone line and are solely in one time zone:CaliforniaNevadaUtahMontanaArizonaColoradoNew MexicoOklahomaIllinoisWisconsinAlabamaGeorgia13 states have some portion (however small) that span two time zones:AlaskaOregonIdahoNorth DakotaSouth DakotaNebraskaKansasTexas (a tiny portion of the pan handle)FloridaTennesseeKentuckyIndianaMichiganThe remaining 25 states have one time zone and do not have borders that match the time zone line.
15 degrees of longitude, on average, but the boundaries may vary to co-incide with local political geography e.g. national or state boundaries.
Lake Ontario is completely within the Eastern Time Zone of North America (UTC-5/UTC-4).
yes
It depends on where you are the time zones do not run I straight lines
A continent to continent convergent boundary does not have a subduction zone.
Time zone borders are often irregular and jagged because they follow political boundaries rather than longitudinal lines. These boundaries are determined by countries, states, or regions to align more closely with their local communities and administrative divisions. As a result, time zone borders may zigzag to accommodate different jurisdictions and interests.
The reason why the time zone lines follow irregular paths rather than straight lines, is to allow a number of small countries and islands to maintain a single time zone rather than being divided by these time zone lines. If an island is not very large, it just seems silly and a needless bother to have two time zones. So we just route the time zone line around it.
