Where in a meander does a river erode sediment and where does it deposit sediment?
In a meander, a river erodes sediment on the outer bank of the bend, where the water flows faster and exerts greater force on the bank. Conversely, sediment is deposited on the inner bank of the bend, where the water flows more slowly, allowing particles to settle. This process creates a distinctive pattern of erosion and deposition that shapes the river's channel over time.

When does a river devlop meanders?
As the river winds from side to side, it tends to erode the outer bank and deposit sediment on the inner bank of the bend. Over time, the meander becomes more and more curved.
How sediment buildup and erosion in a meander can alter the course of a river?
As a river deposits sediment on the inside of a meander and erodes the outside of the meander, the meander migrates toward the outside edge
What is a deposit of sediment that forms on the inside of a stream meander?
A deposit of sediment that forms on the inside of a stream meander is known as a point bar. As water flows around the meander, the velocity decreases on the inside bend, causing sediment to settle and accumulate. Over time, this buildup can create a small, sandy or gravelly landform that may support vegetation and alter the stream's flow dynamics. Point bars are important for habitat diversity and can indicate changes in the river's sediment transport processes.
Is meander erosion or deposition?
A meander is primarily a form of erosion. As a river flows, it can erode the outer bank of a bend (cut bank) through hydraulic action and abrasion. Deposition occurs on the inside of the bend (point bar) where the velocity of the water decreases, causing sediment to be deposited.
What is the inside bend of a river called?
The inside bend of a river is called a "meander." Meanders occur as a result of erosion and sediment deposition along the riverbank, creating a curving or winding pattern in the waterway.
Why have meanders been cut off?
Naturally rivers erode & deposit silt & debris over time, millions of years, and this erosion will, by force of gravity, alter the course of the river. Where there is a large meander, a huge bend in the river course, erosion may be so dramatic that the meander will be cut & this will form a lake in the old river course. This type of semi cirular lake is called an Oxbow lake. It is a cut off meander.
Why does water desposit more on the inside of a meander?
Water deposits more on the inside of a meander due to the reduced flow velocity in that area. As a river bends, the outer bank experiences faster water flow, which can erode the bank and carry sediment downstream. In contrast, the inner bank has slower-moving water, allowing sediment to settle and accumulate. This process creates features like point bars on the inside of the meander.
What is a meander bend?
A meander is a bend in a river which will eventually erode to form an ox-bow lake which is a thing in a river! A meander is formed around a ox-bow lake. Your Welcome!! ;)
Does an old or young river deposit more sediment?
an older river deposits more sediment.
What is another name for a river deposit?
Sediment.
When does a river deposit its load?
When theres a meander or it comes to the mouth also when it comes to a waterfall
What landform is created when a meander is cut off with sediment?
When a meander is cut off from the main river channel, it creates an oxbow lake. This landform is formed as sediment fills in the former meander loop, isolating it from the river. Over time, the oxbow lake may become a wetland or gradually dry out, depending on the local hydrology.
