Primary succession is the series of community changes which occur on an entirely new habitat which has never been colonized before. Examples of such habitats would include newly exposed or deposited surfaces, such as landslips, volcanic lava and debris, elevated sand banks and dunes, quarried rock faces.
  Primary Succession occurs on surfaces where no soil exists, And  Secondary Succession follows a disturbance that destroys a  community without destroying the soil.   Primary succession is slow and secondary succession is rapid.   Primary succession begins in areas where no soil is present.  Secondary succession occurs in areas where there is soil  already present.
