What are part of two important cycles on Earth that are involved in glaciation?
100
This glacier is contained inside a watershed.
What is a Valley Glacier?
100
The zone where glaciers start?
What is the zone of accumulation?
100
It looks like a serrated knife edge.
What is the ridge of an Arete?
100
This moraine is deposited along the sides of the glacier.
What is a Lateral Moraine?
200
Originates on land from the accumulation, compaction, and recrystallization of snow.
How does a glacier start?
200
Another name for Valley Glacier.
What is Alpine Glacier?
200
Increased accumulation and lower temperatures
What are conditions that cause glaciers to grow?
200
It looks like a spike of mountain top.
What is a Horn?
200
This moraine marks the location where the front of the glacier paused in its retreat.
What is a Recessional Moraine?
300
A large persistent body of ice that forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries.
What is a glacier?
300
The largest type of glacier.
What is Continental Glacier?
300
Greater ablation and lower snow fall
What are triggers for shrinking glaciers?
300
This erosional landform is where the glacial accumulation zone happens.
What is a cirque?
300
This moraine is trapped in the ice near the middle of the glacier. It happens when a piedmont glacier meets and combines with a larger glacier.
What is a Medial Moraine?
400
Which of two types of glacier movement is better modeled using flubber?
What is plastic flow?
400
The amount of Earth's fresh water contained in the Antarctic Ice Sheet.
What is 66%?
400
A glacial equivalent to your bank balance.
What is the size of the glacier.
400
This valley ends perched above another larger valley below it.
What is a hanging valley?
400
This moraine is an extensive and nearly continuous layer of till over bedrock.
What is a Ground Moraine?
500
The type of movement that is not modeled well by flubber.
What is basal slip?
500
A glacier formed by the ends of valley glaciers at the bottom of their valleys.
What are Piedmont Glaciers?
500
A glacial equivalent to depositing money into your bank account.
