shows the
Coriolis effect on a merry-go-round. This
demonstration shows from above a spinning merry-go-round the path
the ball travels appears to be straight. However, from the
perspective on the merry-go-round the ball appears to curve to the
left as it moves from person-to-person. Likewise, to a
person sitting on the rotating Earth the path of moving objects
appears to be deflected. [Source:

show how the Coriolis
effect changes wind and ocean current directions.
The Coriolis effect deflects
winds and currents until they are parallel to isobars (lines of
equal pressure), then the pressure gradient balances Coriolis
force. [Source: NASA, Jet
