True or False: Corries are typically found in mountainous regions.
True
Fill in the blank: Corries are also known as _______.
cirques
Which process primarily forms a corrie?
Glacial erosion
What are the characteristic features of a corrie?
A steep back wall, a flat floor, and often a small lake or tarn at the bottom.
Multiple Choice: What is the primary agent of erosion that creates a corrie? A) Wind B) Water C) Ice D) Soil
C) Ice
What is the term for the lake that may form in a corrie?
Tarn
True or False: Corries can only be formed in cold climates.
False
How does the shape of a corrie contribute to its formation?
The bowl shape allows for the accumulation of snow and ice, which enhances erosion.

Back wall
Multiple Choice: Which of the following is NOT a feature of a corrie? A) Glacial meltwater B) Back wall C) Moraines D) Sand dunes
D) Sand dunes
What is the role of freeze-thaw cycles in the formation of a corrie?

Alpine
True or False: Corries can evolve into larger glacial valleys over time.
True
What is the term for the debris left behind by a melting glacier at a corrie’s edge?

A) Valley glacier
What is a common ecological feature found in a corrie?
Unique alpine flora and fauna
Fill in the blank: The process of _______ occurs when glaciers erode the landscape to form a corrie.
Glaciation
What is the effect of climate change on existing corries?
Melting glaciers may reduce the size and shape of corries.
True or False: Corries can be found on every continent.
False
What geographic feature is often formed at the outlet of a corrie?
