Continuos abrasion by wind- blow partiach rzeźb rock surfaces, producing unique shapes found in desert landscapes worldwide.

Glacial erosion shapes distintiva landforms such as U- shaped valleys, fjords (deep coasal inlets), cirques (bowl- shaped depressions), arêtes (sharp ridges), ande hanging valleys. The Gret Lakes in North America owe their origin to repeated glaciations that carved andd depened their basins. Ice erosion is most active in alpine mountain ranges and polar ice sheets.
