Erosion, Transport, and Deposition by Glaciers

Imagine standing in a valley surrounded by towering mountains.
The landscape is shaped by glaciers—massive rivers of ice that erode, transport, and deposit materials as they move.

Note

These processes create some of the most dramatic landforms on Earth.

Glacial Erosion: Carving the Landscape

1. Plucking

Plucking occurs when a glacier freezes onto rocks and pulls them away as it moves.

Note

This process creates striations (scratch marks) and polished rock surfaces.

Note

Plucking and abrasion work together to deepen and widen valleys, transforming them into U-shaped glacial troughs.

Glacial Transport: Moving the Load

Glaciers transport debris, known as moraine, in three main ways:

1. Supraglacial

Debris is carried on top of the glacier, often from rockfalls or avalanches.

2. Englacial

Debris is trapped within the ice, carried along as the glacier moves.

3. Subglacial

Debris is dragged along the base of the glacier, contributing to erosion through abrasion.
