Fiords and glacial lakes
Glacier?
A glacier is a slow-moving river of ice that erodes the landscape over time. Glaciers flow due to gravity, picking up rocks and debris along the way that contribute to erosion. The movement of a glacier can create valleys, fjords, and other unique geological features.
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.
As a glacier moves through a V-shaped river valley, it erodes the valley walls, transforming the V shape into a broader U shape. The immense weight and movement of the glacier scrape and pluck rock and sediment from the sides, leading to steepened and smoothened valley walls. This process also results in the widening of the valley floor, creating a more expansive glacial trough. Over time, the glacier's movement reshapes the landscape, leaving behind features such as hanging valleys and moraines.
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.
In cross-section: A 'U' shaped valley is formed from glacial erosion. A 'V' shaped valley is formed by river erosion.
A river valley forms from a river from the river going into a valley
Corrasion, Hydraulic action, Attrition
is a glacier.
usualy, there is a river flowing through it that erodes it.
