Glaciers that grow in the upper elevation of the mountains get bigger. Scientists say the glaciers are __________________ downslope

• Advancing

• Receding

  (Retreating)

Glaciers that melt at the base of mountains mountains get smaller. Scientists say the glaciers are __________________ upslope

• Advancing

Glacial ice (moving ice) deposition is...

• Sorted, Layered and Organized

• Unsorted, Unlayered and Organized

• Layered, Unsorted and Organized

• Unsorted, Angled, Unlayered and Unorganized

What is this feature?

• Moraine

• Kettle

• Drumlin

• Outwash Plain

What do drumlins tell an observer?

• The direction the glacier moved (they always point North)

• The direction the glacier moved (they always point South)

• How the drumlin formed

• How thick the drumlin is

Drumlins are depositional features of moving ice. What type of sediment do they show?

• Sorted and Organized

• Sorted and Layered

• Unsorted and Layered

• Unsorted and Unorganized

What are these features? These are created when glaciers travel over rock and scratch them with the sediment that has been picked up.

• Drumlins

• Kettles

• Striations

• U Shape Valley

What do striations tell an observer?

• The direction the glacier moved (they are always North/South)

• The direction the glacier moved (they are always East/West

• How the striations formed

• How thick the striations are
