physical  weathering -involves  breaking  of  rocks  into  small  particles. It  happen when  water  enter  into  pores and  crack  the rock  then  freeze.

 Chemical  weathering-happens  when rocks  are  worn  by chemical   changes. It  occurs when  oxygen  and  water  interact  with  the  mineral leading  to  formation  of  new  materials.
