A short distance from the geographic South Pole is a ceremonial South Pole—    5     actual pole with flags from some countries.Far，far away is the magnetic South Pole—the South Pole     6     which a compass would point you.Its current location is 1,800 miles away from the geographic South Pole，in the Southern Ocean，so far north     7     it’s not even in the Antarctic circle.The ocean­going magnetic South Pole is     8     (natural) unmarked，but if you happen to be there，you     9     (notice)：Your compass needle moves aimlessly.
