Glacier Key Terms

HideShow resource information
Freeze Thaw Weathering (FTW)
When melt water enters cracks and expands by 10% causing the rock to shatter
1 of 15
Plucking
When ice freezes to rocks and pulls them out by the movement of the ice frozen to them
2 of 15
Basal slide
Where melt water lubricates the ice so it slides downhill
3 of 15
Internal Deformation
Where ice moves through cracking and breaking
4 of 15
Abrasion
Rocks in the glacier sides and base scrape away at the rock below like sandpaper
5 of 15
Bull-dozing
Where the snout of the glacier pushes through obstacles as the glacier advances
6 of 15
Glacier
A finger of ice found in a mountain valley
7 of 15
Calving
The process where large chunks of ice break off the end of a glacier into the sea. Sudden change
8 of 15
Deposition
Where the glacier drops the material it has been carrying
9 of 15
Ice Sheet
An expanse of ice over 50,000km squared
10 of 15
Ice Cap
An expanse of ice less than 50,000km squared
11 of 15
Zone of ablation
The part of a glacier where the outputs are higher than the inputs
12 of 15
Zone of accumulation
The part of a glacier where inputs are higher than outputs
13 of 15
Glacial Budget
The balance between inputs and outputs determining if a glacier will advance or retreat
14 of 15
Rotational Slip
Where the glacier moves over and erodes a curved surface
