BSL Geography Glossary - Saltation - definition

Saltation is a form of transport for sediment in rivers. Small rocks or pebbles which are too big to be carried within the water are transported and bounce along the bottom of the river bed.

SALTATION: Movement of particles by a series of short bounces along the surface of the ground, and dislodging additional particles with each impact. The bouncing particles ranging in size from 0.1 to 0.5 mm usually remain within 30 cm of the surface.

Saltation is the transportation of sand grains in small jumps by wind or flowing water . ... First, a bed of sand grains must be covered by flowing air or water, as in a streambed or windy desert .

Bedload: the material carried by a river by being bounced or rolled along its bed.

In geology, saltation (from Latin saltus 'leap, jump') is a specific type of particle transport by fluids such as wind or water. It occurs when loose materials are removed from a bed and carried by the fluid, before being transported back to the surface.

Definition of surface creep

: a stage in the wind erosion process in which sand grains are moved along the ground surface by impact of other grains in saltation.

Traction - large, heavy pebbles are rolled along the river bed. ... Suspension - lighter sediment is suspended (carried) within the water, most commonly near the mouth of the river. Solution - the transport of dissolved chemicals. This varies along the river depending on the presence of soluble rocks.

In biology, saltation (from Latin saltus 'leap, jump') is a sudden and large mutational change from one generation to the next, potentially causing single-step speciation. ... Speciation, such as by polyploidy in plants, can sometimes be achieved in a single and in evolutionary terms sudden step.

Climate and topography are two important factors in soil formation. ... These are the main driving forces that affect weathering which eventually is the building block of soil itself. Precipitation has a great influence on soil because the intensity and distribution of rainfall determines the weathering of soil.
