Can a glacier create narrow valley?

Yes, a glacier can create a narrow valley, known as a glacial trough or glacial valley. Glaciers are large masses of ice that move slowly over the land, and as they do, they erode and shape the landscape. They can carve out deep, narrow valleys with steep sides. The process of glacial erosion occurs when the ice at the base of the glacier freezes to the bedrock below and then moves, dragging the rock along with it. This process is called plucking. Additionally, the ice can also abrade the bedrock, grinding it down into smaller particles.
