Fiords and glacial lakes
A frozen river that erodes slowly is called a glacier.
Glacier?
A U-shaped valley begins as a V-shaped river valley. If the temperature is low enough, a glacier (river of ice) forms inside the valley. As the glacier slowly moves, it scours the valley floor when the temperature rises and the glaciers melts away, a U-shaped valley is left behind.

The running water in the river erodes the landscape.When the river tumbles at steep angle over very hard rocks or down a steep valley side it forms a waterfall
The shape of a valley carved by a glacier is U shaped. A valley carved by a river is V shaped.
A river valley forms from a river from the river going into a valley
Corrasion, Hydraulic action, Attrition
usualy, there is a river flowing through it that erodes it.
is a glacier.
a glacier is ice. ice forms a landform called a mouth of a river
Basically it's a river just like any other so what it does is erode a channel through the mountains. Thing is, instead of making a "V" shaped valley like a liquid river would, a glacier makes a "U" shaped valley. When the glacier retreats, the steep slopes collapse pretty readily so you get landslides everywhere. Alternatively, if the sea rises, the valley forms a fiord (ala Milford Sound in New Zealand).
