TIME
why the time is different in different
countries?
As Earth rotates, different parts of Earth receive
sunlight or darkness, giving us day and night. As
your location on Earth rotates into sunlight, you see
the sun rise. ... Since different parts of Earth enter
and exit daylight at different times, we
need different time zones.

the south pole in the Earth’s model sphere
are also known as longitudes
The lines drawn horizontally in the center of
the model sphere is latitude
Latitude and Longitude
lines are used to
accurately and precisely
