Instructions
* Fill in the missing words into the blank fields
Erosion  is  a  process  by  which  the  surface  of  the  earth  is  worn  away  by  naturally  occurring  or  man-made  .  If  you  look  at  any  coastline,  you  will  be  able  to  observe  how  the  continual  pounding  of  the  wind  and    has  caused  erosion  of  the  rocky  surfaces,  leaving  behind  many  different  kinds  of  structural  landmarks,  cliffs  and  .  Soil,  or  more  specifically,  the  top  layer  of  the  soil,  is  also  subject  to  erosion  by  water,  wind  and  some  farming  practices,  although  often  it  is  not  so  dramatically  visible  to  the  naked  eye.  It  is,  nevertheless,  of  great  importance,    to  farmers  because  this  top  layer  of  the  soil  is  the  most  fertile,  containing  an  organic,  nutrient-rich  mixture  of  materials.  Farmers  need  to  protect  this  subsoil  if  they  want  to    crop  production  and  ensure  extensive  grazing  areas  for  their  cattle.
