Bedrock river

Index Bedrock river

A bedrock river is a river that has little to no alluvium mantling the bedrock over which it flows. [1]

Abrasion (geology)

Abrasion is a process of erosion which occurs when material being transported wears away at a surface over time.

Alluvial river

An alluvial river is river in which the bed and banks are made up of mobile sediment and/or soil.

New!!: Bedrock river and Alluvial river · See more »

Alluvium

Alluvium (from the Latin alluvius, from alluere, "to wash against") is loose, unconsolidated (not cemented together into a solid rock) soil or sediments, which has been eroded, reshaped by water in some form, and redeposited in a non-marine setting.

American Geophysical Union

The American Geophysical Union (AGU) is a 501(c)(3) nonprofit organization of geophysicists, consisting of over 62,000 members from 144 countries.

Bed load

The term bed load or bedload describes particles in a flowing fluid (usually water) that are transported along the bed.

Bedrock

In geology, bedrock is the lithified rock that lies under a loose softer material called regolith at the surface of the Earth or other terrestrial planets.

New!!: Bedrock river and Bedrock · See more »

Carbonate rock

Carbonate rocks are a class of sedimentary rocks composed primarily of carbonate minerals.

Cohesion (geology)

Cohesion is the component of shear strength of a rock or soil that is independent of interparticle friction.

New!!: Bedrock river and Cohesion (geology) · See more »

Conservation of energy

In physics, the law of conservation of energy states that the total energy of an isolated system remains constant, it is said to be ''conserved'' over time.

Dissolved load

Dissolved load is material, especially ions from chemical weathering, that are carried in solution by a stream.

New!!: Bedrock river and Dissolved load · See more »

Erosion

In earth science, erosion is the action of surface processes (such as water flow or wind) that remove soil, rock, or dissolved material from one location on the Earth's crust, and then transport it to another location (not to be confused with weathering which involves no movement).

Fluvial

In geography and geology, fluvial processes are associated with rivers and streams and the deposits and landforms created by them.

New!!: Bedrock river and Fluvial · See more »

Glacier

A glacier is a persistent body of dense ice that is constantly moving under its own weight; it forms where the accumulation of snow exceeds its ablation (melting and sublimation) over many years, often centuries.

Grade (slope)

The grade (also called slope, incline, gradient, mainfall, pitch or rise) of a physical feature, landform or constructed line refers to the tangent of the angle of that surface to the horizontal.

Gravitational energy

Gravitational energy is the potential energy a body with mass has in relation to another massive object due to gravity.

New!!: Bedrock river and Gravitational energy · See more »

Headward erosion

Headward erosion is erosion at the origin of a stream channel, which causes the origin to move back away from the direction of the stream flow, and so causes the stream channel to lengthen.

New!!: Bedrock river and Headward erosion · See more »

Kinetic energy

In physics, the kinetic energy of an object is the energy that it possesses due to its motion.

New!!: Bedrock river and Kinetic energy · See more »

Plate tectonics

Plate tectonics (from the Late Latin tectonicus, from the τεκτονικός "pertaining to building") is a scientific theory describing the large-scale motion of seven large plates and the movements of a larger number of smaller plates of the Earth's lithosphere, since tectonic processes began on Earth between 3 and 3.5 billion years ago.

Plucking (glaciation)

Plucking, also referred to as quarrying, is a glacial phenomenon that is responsible for the erosion and transportation of individual pieces of bedrock, especially large "joint blocks".

River

A river is a natural flowing watercourse, usually freshwater, flowing towards an ocean, sea, lake or another river.

New!!: Bedrock river and River · See more »

River incision

River incision is the narrow erosion caused by a river or stream that is far from its base level.

New!!: Bedrock river and River incision · See more »

Saltation (geology)

In geology, saltation (from Latin saltus, "leap") is a specific type of particle transport by fluids such as wind or water.

New!!: Bedrock river and Saltation (geology) · See more »

Sandstone

Sandstone is a clastic sedimentary rock composed mainly of sand-sized (0.0625 to 2 mm) mineral particles or rock fragments.

New!!: Bedrock river and Sandstone · See more »

Sediment

Sediment is a naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of wind, water, or ice, and/or by the force of gravity acting on the particles.

New!!: Bedrock river and Sediment · See more »

Solubility

Solubility is the property of a solid, liquid or gaseous chemical substance called solute to dissolve in a solid, liquid or gaseous solvent.

New!!: Bedrock river and Solubility · See more »

Stream load

Stream load is a geologic term referring to the solid matter carried by a stream (Strahler and Strahler, 2006).

New!!: Bedrock river and Stream load · See more »

Stream power

Stream power is the rate of energy dissipation against the bed and banks of a river or stream per unit downstream length.

New!!: Bedrock river and Stream power · See more »

Suspended load

The suspended load of a flow of fluid, such as a river, is the portion of its sediment uplifted by the fluid's flow in the process of sediment transportation.

New!!: Bedrock river and Suspended load · See more »

Traction (geology)

Traction is the geologic process whereby a current transports larger, heavier rocks by rolling or sliding them along the bottom.

New!!: Bedrock river and Traction (geology) · See more »

Upland and lowland

Upland and lowland are conditional descriptions of a plain based on elevation above sea level.
