What else can I help you with?
The stream load that includes gravel and large rocks is the?
bed load. This type of stream load consists of heavier materials that are transported along the stream bed through rolling, sliding, or bouncing. It tends to move more slowly than suspended load or dissolved load.
How does water transport and deposit the materials that it has weathered?
Water transports weathered materials through erosion by carrying them downstream, either in suspension, solution, or as bed load. When the water's energy decreases, it deposits these materials, creating sedimentary layers in areas such as riverbeds, floodplains, deltas, or oceans. Factors like velocity, volume, and sediment size influence how water transports and deposits these materials.
What affects the amount of sediments a river can carry?
The amount of sediments a river can carry is influenced by factors such as the river's velocity, volume of water, slope of the river bed, sediment particle size, and the presence of vegetation or structures that can trap sediments. Increased velocity and water volume typically result in higher sediment transport capacity.
What are pebbles and boulders carried in a stream called?
A stream can bounce large pebbles and boulders, along the stream bed. These rocks are called bed load. A stream can carry sand in suspension. These materials, called suspended load, make the river look muddy. The dissolved load is material carried in a solution, which means that the material is dissolved in the water. Sodium and calcium are some of the materials in the dissolved load.
What is the total sediment load transported by a stream?
The total sediment load transported by a stream is the sum of the bed load, suspended load, and dissolved load. Bed load consists of larger particles that roll, slide, and bounce along the streambed. Suspended load is finer particles carried in the water column, while dissolved load is material that is dissolved in the water itself.
Does river load size decrease?
The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape. Brap brap !!
Why does bed load decrease in size?
The bedload becomes smaller when the river is flowing downstream, and the rocks also become smaller, smoother and rounder due to attrition and abrasion. (The reason the flow slows down is because the energy of the flow decreases.)

Why why does bed load change as it goes downstream?
The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape. Brap brap !!
How do stream transport sediments?
Stream transport sediment in three ways, dissolved load, (ions in solution being carried downstream), suspended load, (suspended sediment that floats freely downstream) and bed load, (sediment that rolls or scoots along the bottom of the river).
How would size of the sediment in the streams load differ in the streams volume increasing or decreasing?
The size of the sediment would decrease further downstream (where there is a greater volume of water) as there is more energy in the flow. Therefore more erosion will occur and the sediment will rub together with other materials i.e other rocks or the river bed (this is called attrition). The sediment will therefore reduce in size but there will be a greater amount of it. (The amount of sediment is called the discharge.)
How does the bed load affect the erosion?
Bed load can increase erosion by entraining and transporting sediment along the streambed, causing abrasion and scouring of the channel bed. The movement of sediment in the bed load can also contribute to sediment transportation and deposition in downstream areas, altering the overall balance of sediment in the stream system and potentially leading to changes in channel morphology and erosion patterns.
What are An upward decrease in grain size in a single bed is known as?
Cross bedding
What is the difference between a streams suspended load and its bed load?
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.
What is the difference between a river's suspended load and its bed load?
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.
What and the difference between a rivers suspended load and it and bed load?
The difference between a suspended load and a bead load is a suspended load consists of the small particles or rock materials that are dispersed throughout the water and easily carried downstream. The bead load consists of the larger particles that are dragged and bounced along near the bottom of the river.
