What is ablation?
Outputs from the glacier budget, such as melting.
2 of 18
What is the glacier budget?
The balance between the inputs (accumulation) and the outputs (ablation) of a glacier.
3 of 18
What is calving?
Chunks of ice falling off a glacier.

What is plucking?
Individual rocks are plucked from the valley floor or sides as water freezes them to the glacier.

What is deposition?
Deposition occurs when the ice melts and the bulk of the material is deposited, (mostly) at the snout.

What is a moraine?
Sediment carried and deposited by the ice like a giant conveyer belt.

What is a hanging valley?
A tributary glacial trough perched up on the side of the main valley, often marked by a waterfall.

What is a ribbon lake?
A long narrow lake in the bottom of a glacial trough.

What is a lateral moraine?
A ridge of frost shattered sediment running along the edge of a glacier where it meets the valley sode
16 of 18
What is the medial Moraine?
A ridge of sediment running down the centre of s glacier formed when two lateral moraines merge.
17 of 18
What is a terminal moraine?
A high ridge running across the valley representing the maximum advance of a glacier.
