Answer 1

The  three  type  of  weathering  are  biological,  physical  and  chemical  weathering. 

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.

 biological  weathering-  is  disintegration of  rocks  as  result of  action  by  living  organism. example  tress.

An  outwash  is  large  quantities  of  water  that flow from  melting  ice.  The  material  deposited  are  sand  and  other  fine  sediment.

Answer 2

Hello!

1) Three type of weathering and erosion caused by glaciers are plucking, abrasion and freeze thaw.

2) Plucking causes erosion by scraping the ground when the glacier moves, abrasion causes erosion by the sand in water. When the sand filled water smashes against cliffs and hills it acts like sand paper and erodes the ground. Freeze thaw erodes rocks and cliffs by water. water gets into cracks of rocks and when the water freezes it expands and breaks the rock into pieces.

3) The large quantities of water that flowed from the melting ice deposited various kinds of materials, the most important of which is called glacial outwash . Outwash plains made up of outwash deposits are mostly flat and consist of layers of sand and other fine sediments.

Hope it helps!
