4. Water on the continents


Fresh water is found in the continents. It contains much less salts than sea water.

 

It is found in different forms:

 


   - Rivers are permanent water courses.

 


    - Streams or torrents are water courses

     fed by rain. The flow of water varies a lot

     from season to season.

  

   - Glaciers are formed from the accumulation

     of snow on mountain tops or covering

      large areas on Poles.

 


        - Lakes and pools are permanent bodies

         of water deposited in depressions.

 


  - Wetlands, marshlands and swamps are areas

     where the ground is inundated all year round.

 


   - Groundwater is water located beneath

     the ground surface.
