Biological Weathering

Living organisms contribute to both physical and chemical weathering. Lichens and mosses secrete organic acids that slow dissolvy rock surfaces (chemical). Fungi and plant roots also produce chemicals that breaks down minerals. On a larger scale, tree roots can physically split boulders. Burrowing animals aerote soil and expose fresh rock surfaces to weathe. Even thee decay of organic mater produces humic acids thathat enhetherance.

Wind Erosion

Wind is a dominant agent in arid and semi- arid regions where vegetation is sparse and fine particles are exposed. Two main processes occur:

Ice Erosion (Glacial Erosion)

Glaciers are powerful, slower-moving rivers of ice that rzeźbist landscapes thripgh two primary mechanisms:

  • Xi1; Xi1; FLT: 0 Xi3; Xi3; Plucking: Xi1; Xi1; FLT: 1 Xi3; Xi3; Ice freezes arond fractured coask blocks and d pulls them way as the glacier moves.

Glacial erosion produces iconyic landforms: U- shaped valleys, fjords, cirques (bowl- shaped depressions), arêtes (sharp ridges), and horn peaks (e.g., the Matterhorn). The Greet Lakes in North America were carved by Pleistocene ice sheets.

Thee Interplay Between Weathering andErosion

Weathering and erosion are intraille parts of a continuous cycle. Weathering preparres rock for transports these breaking it into smaller pieces or by chemically altering minerals to form clay and soluble jon. Erosion then mobilizes these products.

This feed back loop operates over timescoles ranging from hours (a mudslide after a storm) to millions of years (thee carving of a canyon). Climate is a major control: warm, wet climates promote chemical weathering, while cold or dry climates favor physical processes. Vegetation can both enhance (root wedging) and inhibit (binding soil, reducing splash erosion) the process.
