Which term describes the sediment load transported by a stream?
The maximum load of sediment that a stream can transport is called its capacity. Capacity is directly proportional to the discharge: the greater the amount of water flowing in the stream the greater the amount of sediment it can carry.

Which of the following rivers has the largest water discharge of any in the world?
The correct answer is Amazon. The Amazon is the largest water source for fresh water in the world. The Amazon river discharge is about 209,000…
What term describes the particle transport mode that is intermediate between suspension and rolling along the bottom of streams?
Hydrologic cycle. What term describes the particle transport mode that is intermediate between suspension and rolling along the bottom of streams? This process also moves sand grains in a sand dune. Saltation. You just studied 25 terms!
What is bed load and suspended load?
The bed load consists of the larger sediment which is transported by saltation, rolling, and dragging on the riverbed. The suspended load is the middle layer that consists of the smaller sediment that's suspended.
What is the load of a stream?
Stream load is a geologic term referring to the solid matter carried by a stream (Strahler and Strahler, 2006). Erosion and bed shear stress continually remove mineral material from the bed and banks of the stream channel, adding this material to the regular flow of water.
What determines the maximum sediment load of a stream?
Capacity and competence. The maximum load of sediment that a stream can transport is called its capacity. Capacity is directly proportional to the discharge: the greater the amount of water flowing in the stream, the greater the amount of sediment it can carry.
What is stream abrasion?
Abrasion occurs as sediment in a stream collides with rock in and along the stream. Pieces of rock are chipped away and rough edges in rocks and sediments themselves become rounded. The bedrock beneath streams is also eroded by abrasion. Sediment flowing in the water can cut deeply into the bedrock.
What term generally refers to the highest percentage of the annual sediment load moved by a stream quizlet?
what term generally refers to the highest percentage of the annual sediment load moved by a stream? suspended load.
Which of the following rivers has the largest annual discharge?
List of rivers by discharge
| No | Continent | River |
|---|---|---|
| 1 | South America | Amazon |
| 2 | Africa | Congo (Zaire) |
| 3 | Asia | Ganges-Brahmaputra/Meghna |
| 4 | South America | Orinoco |
What term describes the movement of water through earth’s hydrosphere?
The water cycle describes how water is exchanged (cycled) through Earth's land, ocean, and atmosphere. Water always exists in all three places, and in many forms—as lakes and rivers, glaciers and ice sheets, oceans and seas, underground aquifers, and vapor in the air and clouds.
Where is erosion concentrated along a meandering stream quizlet?
Where is erosion concentrated along a meandering stream? On the outer parts of the meander loops or bends.
What are types of sediment loads?
When particles are eroded and transported by wind, water, or ice, they become part of the transport medium's sediment load. There are three categories of load that may be transported by an erosional agent: dissolved load, suspended load, and bedload.
What is sedimentation load?
The amount of sediment that is transported through a stream cross section over one year, which includes chemicals carried in solution (the dissolved or solution load), small particles carried in suspension (the suspended load), and larger particles that are rolled along the river bed (the bedload).
Where is the highest average stream velocity?
Stream velocity is greatest in midstream near the surface and is slowest along the stream bed and banks due to friction.
What are the 3 types of stream load?
Stream load is broken into three types: dissolved load, suspended load, and bed load (Ritter, 2006).
What is abrasion and attrition?
Abrasion occurs as a result of two surfaces rubbing against each other resulting in the wearing down of one or both of the surfaces. However, attrition refers to the breaking off of particles (erosion) which occurs as a result of objects hitting against each other.
What does attrition mean in geography?
Attrition is when material such as rocks and stones carried by waves hit and knock against each other wearing them down. As these materials are worn down sand and rounded beach pebbles are formed. Cliffs. Sea cliffs are one of the clearest examples of sea erosion that we can see.
What is the suspended load of a stream?
Almost all the world's streams carry sediment that originates from erosion processes in the basin that feed the streams. Sediment carried in a stream is classified as either suspended load or bed load. The suspended load is the fine-grained (clay and silt) sediment that remains in water during transportation.
What is a floodplain quizlet geology?
What is a floodplain? a flat surface next to a river channel. What is a natural levee? a ridge of flood deposits next to a river channel.
What river has the highest flow rate?
the Amazon The greatest flow of any river in the world is that of the Amazon, which discharges an average of 200,000 m³/sec (7,100,000 ft³/sec) into the Atlantic Ocean, increasing to more than 340,000 m³/sec (12,000,000 ft³/sec) in full flood.
What is a high river discharge?
0:333:14River Discharge – YouTubeYouTube
What is a stream load quizlet?
Stream load. All the materials that are transported in a stream. Dissolved load.
What is precipitation in water cycle?
Precipitation is water released from clouds in the form of rain, freezing rain, sleet, snow, or hail. It is the primary connection in the water cycle that provides for the delivery of atmospheric water to the Earth. Most precipitation falls as rain.
What is suspended load quizlet?
Suspended load is. Fine sand, silt, and clay particles in suspension. bed load is. particles that are too heavy to be carried in suspension that roll or bounce along the bottom.
Where is stream erosion concentrated along a meandering stream?
Where do deposition and erosion of material occur along a meander? Deposition occurs on the inside of the meander, whereas erosion occurs on the outside.
What is the largest sediment that can be transported by a stream?
Sediment moved by water can be larger than sediment moved by air because water has both a higher density and viscosity. In typical rivers the largest carried sediment is of sand and gravel size, but larger floods can carry cobbles and even boulders.
Where is the highest average stream velocity quizlet?
Velocity is highest in the center where friction is lowest. Which statement about lateral migration is true? Streams migrate opposite the direction of erosion.
What are types of sediment load?
When particles are eroded and transported by wind, water, or ice, they become part of the transport medium's sediment load. There are three categories of load that may be transported by an erosional agent: dissolved load, suspended load, and bedload.
What is abrasion and Corrasion?
abrasion (corrasion) The erosive (see EROSION) action that occurs when rock particles of varying size are dragged over or hurled against a surface. Some common agents of abrasion are the bed load of streams, rock debris embedded in the bases of glaciers, and sand and shingle transported by wind or waves.
