Beauvais  Lake  Landforms  By  Teigen  

Land  forms

A  landform  is  a  feature  on  the  Earth's  surface  that  is  part  of  the  terrain,  such  as  mountains,  hills,  and  plains.

Beauvais  Lake

Beauvais  Lake

Beauvais  lake  is  2.5km  long  and  is  4.6km  wide,  making  an  area  of  11.5km  squared.  Its  has  a  volume  of  3.8  million  meters  cubed  and  a  depth  of  10.7m.  The  park  was  created  in  1940,  but  didn’t  include  the  lake,  which  became  part  of  the  park  in  1959.  

Ridges

Ridge

The  ridges  in  Beauvais  lake  were  formed  by  plate  tectonics,  which  are  when  huge  bits  of  the  Earths  crust  (called  tectonic  plates)  move  and  crash  into  each  other.  This  sometimes  forms  mountains  but  it  also  forms  volcanoes,  earthquakes,  and  islands.

Outcrop

Outcrop

The  outcrops  in  Beauvais  Lake  were  originally  sandstone,  which  is  a  type  of  rock  that  is  made  of  sand  that  a  long  time  ago  was  crushed  into  solid  rock  by  the  weight  of  the  earth.  Then  giant  pieces  of  moving  ice  called  glaciers  moved  through  the  area  and  took  some  of  the  rock  with  them.  Eventually,  this  resulted  in  the  outcrops  you  see  today.

Gully

Gullies

Gullies  can  look  like  valleys  or  canyons,  but  are  only  about  10  meters  wide  or  deep.  They  are  caused  by  erosion,  which  is  when  natural  things  like  water  or  wind  remove  soil,  rock,  or  other  dissolved  material.  

Land  Forms

Thinking  about  landforms  might  seem  a  scientific  endeavour  but  not  a  bad  thing  to  ponder  for  a  few  moments.    The  land  forms  we  have  at  Beauvais  are  what  give  us  what  we  enjoy  so  much  in  this  small  lake  with  the  multiple  converging  ecosystems  and  the  immense  diversity  of  accompanying  life  forms.    

Enjoy  the  land  forms.
