| In this
global map of the geoid (Geoid99), the area
in red in the South Pacific just north of
Australia indicates a region where the Earth's
gravitational pull is stronger. Here, the
mean sea level is higher because the hypothetical
ocean has been pulled towards this area where
gravity is stronger. In fact, if you stood
at sea level in the area near India (where
the Earth's gravity is weaker) you would
be a little bit lighter than if you stood
at sea level just north of Australia in the
South Pacific where the Earth's gravitational
force is stronger. |
