SUMMARY:  Explores  three  theories  of  mountain  forma-
tion: that  as  the  Earth  cooled,  it  shrank  and  wrinkled  up  to
form  mountains;  that  the  Earth  is  expanding  and  this  expan-
sion creates  cracks  which  allow  mountains  to  build  up  by
volcanic  action;  and  that  convection  currents  circulate  in  the
Earth's  heated  mantle  to  create  mid-ocean  ridges,  shoving
continents  and  plates  in  the  crust  to  form  mountains.
