Exam 14: Glacial and Periglacial Landforms

Soil, regolith, and bedrock at a temperature that remains below 0°C (32°F)on a perennial basis is the catalyst that can produce:

A thin layer of till that blankets the landscape after a glacier melts is called:

_____________________ is a hill or mound of water-laid sediment found on the outwash plain.

All till is drift, but not all drift is till.

Loess is a type of till.

The man BEST noted for graphing insolation changes on Earth through time in an attempt to understand Pleistocene climatic patterns is:

One important hypothesis about the cause of the recent Ice Age involves:

Ground moraine is made of till.

On the illustration, the landform at D is a(n):

When intersecting cirques carve away the mountain, steep peaks called what are formed?

___________________ is small lake found at the bottom of a cirque.

____________________ consists of layers of sorted and stratified clays, silts, sands or gravels.

When the troughs of tributary glaciers lie above sea level, these hanging valleys can create:

Continental ice sheets are associated with:

The landform at C is a(n):

When the floors of lesser troughs lie above the sea level of the main trough, they are called:
