Glacial Erosion

Glacier = river of 

• ice

• sediment

Freeze-thaw weathering a.k.a.

• frost action

• good times

rock bumping into other rocks = 

• frost action

• abrasion

Glaciers may look dirty because

• they do not shower often. 

• rock is frozen in it.

rocks no longer moved by the glacier and dropped off at Earth's surface = 

• weathering

• erosion

• deposition

nature's bulldozer = 

• wind

• waves

• glaciers
