  5. 5. -It is when ice freezes and sticks to rock. When the ice moves, large pieces of rock are pulled away with it. Corries -They are also known as cirques or chums. They are deep, rounded hollows with a steep back wall and a rock basin.
  6. 6. -In most cases, glacier is along an existing river valley, eroding both the floor and the sides of the valley to form a glacial trough. -The characteristic V-shape of a river valley is turned into the typical U-shape of a glaciated valley.
