Through   gravitational  compression,  earth  layers  were  formed  by process  called density  stratification.   this  process  describe  the  layer  of  water in  a    body  of  water  with  a  layer   of  cold  dense  water  at  the  bottom were  the temperatures  are  above freezing point, A  water  layer  float  on  top and  when  the  water  on  the  surface  coll  to  about  4  degrees  it sinks
