The earthÕs
curved surface means that objects are moving at
very different speeds depending on
their latitude:
At the equator
(latitude 0¡), an object is moving at a
speed of about 1700
km/hr.
At the pole
(latitude 90¡), an object moving
hardly at all due to the
earthÕs rotation.
Here in Los
Angeles (latitude 34¡N),
an object is moving at a
speed of about 1400
km/hr (=860 miles/hr!).
