Supposedly, the Earth's zero (or reference) meridian is located at
Greenwich, England. Progressing around the globe from the meridian,
time changes one hour with each change of 15 degrees in longitude. The
five time zones in the mainland United States roughly follow those
longitude lines.
However, the Earth's axis is tilted from perpendicular to the plane of the
ecliptic by 23.45, which gives us the four seasons of the year - spring,
summer, autumn (fall) and winter. Since the axis is tilted, different parts
of the globe are oriented towards the Sun at different times of the year.
Wouldn't this mean that Greenwich, England isn't always the ONE spot
on earth where the day begins? Wouldn't it be a different place now and
then? If so, then where would that place be?
A: It's always Greenwich, England
B: Sometimes it's someplace else |
