U-shaped valley. Look at pictures of the Yosemite Valley.
A 'V' shaped valley has been formed by a stream or river. A 'U' shaped valley has been formed by the action of a glacier. Therefore, should a glacier form in the mountains, the ice, pushed downhill by the weight of fresh snow constantly being added high above, will gouge out the 'V' shaped river valley and form the 'U' shaped glacial valley.
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.
You can transform a v-shaped valley into a u-shaped valley by a glacier.

When the glacier is moving down the side of the valley it scrapes of the rocks. The grinding changes the shape of the valley so that it is rounded.
A stream valley is usually 'V' shaped, formed by erosion from a stream. A glacial valley is usually 'U' shaped, formed by the action of a glacier.
A U-Shaped Valley is formed by glacial erosion.
Valley glaciers melt and it make a U shaped profile (cirque) ~W
