* How it happens: As a glacier moves, it freezes to the bedrock below. As the glacier continues to move, the ice pulls on the bedrock, causing it to break apart. This process is aided by the presence of water at the base of the glacier, which can seep into cracks and freeze, expanding and further weakening the rock.
* Result: The broken rock fragments (known as "quarried blocks") are then embedded in the glacier and carried away, leaving behind a jagged, irregular landscape.
Here are some characteristics of plucking:
* Formation: It often occurs in areas with pre-existing fractures or weaknesses in the bedrock.
* Appearance: Plucking creates steep-sided valleys, cirques (bowl-shaped depressions), and jagged peaks.
* Impact: It contributes significantly to the sculpting of alpine landscapes.
