A glacier trough is also known as a U-shaped valley and is formed when a glacier passes through it. The glacier erodes the bottom of the valley through abrasion, and the sides of the valley through freeze-thaw weathering. It wears away the softer rock but when it gets to the harder, tougher rock it can't erode it to give the glacial trough its shape. Hope this helps!
