Features carved by glaciers:

* U-shaped valleys: Glaciers carve out wide, U-shaped valleys with steep sides, unlike the V-shaped valleys formed by rivers.

* Cirques: Bowl-shaped depressions at the head of a glacier, often containing a lake.

* Aretes: Sharp, jagged ridges formed when two cirques erode back-to-back.

* Horns: Sharp, pointed peaks formed when three or more cirques erode together.

* Fjords: Deep, narrow inlets of the sea formed when glaciers carve out valleys and the sea level rises.

* Striations: Scratches and grooves carved into bedrock by rocks embedded in the glacier's base.

The feature NOT carved by glaciers is:

* V-shaped valleys: V-shaped valleys are carved by rivers, not glaciers.
