Arête - GCSE Geography Definition

Reviewed by: Bridgette Barrett

Last updated

An arête is a sharp, knife-edged ridge found in mountainous areas. Formed by the process of glaciation an arête occurs when two neighbouring glaciers erode parallel U-shaped valleys, carving away the rock on either side and creating a narrow, steep-sided ridge in between. They are significant in GCSE Geography as they illustrate the power of glacial erosion and are often used as examples when studying glacial landforms and landscapes.
