The boundary between bed load and suspended load is not straightforward because whether a particle is in suspension or not depends on the flow velocity – it is easy to imagine a particle moving between bed load, part-suspension and full suspension in a fluid with variable flow. Suspended load generally consists of fine sand, silt and clay ...
This glossary of geography terms is a list of definitions of terms and concepts used in geography and related fields, including Earth science, oceanography, cartography, and human geography, as well as those describing spatial dimension, topographical features, natural resources, and the collection, analysis, and visualization of geographic ...
Depending on the balance of these forces, particles may either creep (roll) across the surface until they settle due to a loss of velocity; hop from point to point; or be suspended entirely in the air. These means of sediment transport can be classified as deposition, saltation, and suspension, respectively. Once sediment transport begins, it ...
Bed load sediment in the thalweg of Campbell Creek in Alaska.. The term bed load or bedload describes particles in a flowing fluid (usually water) that are transported along the stream bed.

A dust storm, also called a sandstorm, is a meteorological phenomenon common in arid and semi-arid regions. [1] Dust storms arise when a gust front or other strong wind blows loose sand and dirt from a dry surface.
Deflation is divided into three categories: (1) surface creep, where larger, heavier particles slide or roll along the ground; (2) saltation, where particles are lifted a short height into the air, and bounce and saltate across the surface of the soil; and (3) suspension, where very small and light particles are lifted into the air by the wind ...
Also called Indianite. A mineral from the lime-rich end of the plagioclase group of minerals. Anorthites are usually silicates of calcium and aluminium occurring in some basic igneous rocks, typically those produced by the contact metamorphism of impure calcareous sediments. anticline An arched fold in which the layers usually dip away from the fold axis. Contrast syncline. aphanic Having the ...
