Question

time zone boundaries do not always line up perfectly with lines of longitude. why? keyboard help

Explanation:

Time zone boundaries deviate from longitude lines mainly due to human and political factors. Countries or regions often adjust time zones to align with administrative, economic, or social needs (e.g., keeping a city/region in one time zone for business, governance, or community cohesion), rather than strictly following longitudinal divisions. Also, geographical features like mountains or coasts can influence adjustments, but the primary driver is human organization (e.g., a country may want all its territory in one time zone despite crossing longitudes, or split a region to match economic ties).

Answer:

Time zone boundaries deviate from longitude lines primarily due to human - political and administrative factors. Countries/regions adjust time zones to meet economic (e.g., business coordination), governance (e.g., unified administration), or social (e.g., community cohesion) needs. For example, a country may keep all its territory in one time zone despite crossing longitudes, or split a region to align with economic ties. Geographical features can also play a role, but human - made considerations (like political boundaries, economic zones) are the main reason for not strictly following longitudinal divisions.
