Traction: Where larger rocks/boulders are rolled along the river bed by the underwater currents.

Saltation: When small pebbles are too big to be carried by the river are bounces and rolled along the riverbed.

Solution: When particles dissolve into the water and are carried down.

Suspension: When small pebbles are suspended in the center of the river and follow the current down.

scsl26 — 2025-01-20 04:20:40 UTC

towards the source of the river the cross sectional area is smaller as the shape of the river is like a V. As the river reaches the middle basin there is more erosion taking place on the banks and bed causing it to grow and the rate of discharge to increase. This continues to happen towards the lower basin, the river is much wider and deeper, causing there to be less friction and the velocity to be higher.

Kaede

kaedekarnasuta — 2025-01-20 04:20:41 UTC

Lateral erosion erodes the river horizontally at the sides of the river bank widening the river. Vertical erosion erodes the river vertically and wears away at the river bank causing the river to be deeper.

Traction, saltation, suspension, and solution. Traction involves the rolling or dragging of large particles, like boulders, along the riverbed. Saltation refers to the hopping or bouncing motion of smaller particles, such as pebbles. Suspension is the process in which fine particles, like silt and clay, are carried within the water Solution is transportation of dissolved minerals, like calcium carbonate.

Verticle erosion is when the riverbed cuts downwards due to erosion in the uppercourse where the rock is harder. Lateral erosion is when the riverbank erodes sideways because the banks are made of soil and debris which are easily eroded by fast moving currents.

Aayush

aaja26 — 2025-01-20 04:21:26 UTC

Vertical erosion- Erodes the river vertically causing the river to be deeper

Lateral erosion- Erodes the river horizontally, widening the river

In the upper course of the river near its course, the cross sectional area is V-shaped. The river is shallow and has steep river banks. In the middle course, the river gets deeper and wider and eventually near the mouth it is the widest.

going downstream, the quantity and size of the bedload goes down from erosion, mainly because river velocity slows down

Traction - large rocks that roll along the river bed as there is not enough energy to be carried with the water.

Saltation - smaller rocks and pebbles that bounce along the river bed.

Brook

Vertical erosion is deepening of the river channel, driven by the force of water on the riverbed. This type of erosion occurs when the river's energy is focused on removing materials from the channel floor, causing the river to become deeper over time. Lateral erosion is the erosion of the riverbanks, causing the river to widen.

The bedload of a river increase as it moves down from the source to the mouth because more pebbles and rocks are dissolved into the water and broken down into silt which is carried down easier. The bedload by the source is usually made up of large boulders and rocks and by the mouth the bedload is made up of silt, debris and minerals dissolved into the water.

Nana

piwa26 — 2025-01-20 04:23:16 UTC

Traction: Large boulders and rocks rolled along the riverbed

Saltation: Smaller pebbles and gravel are bounced along the riverbed

Solution: Soluble materials are dissolved in the water

thais

as it moves downstream, the volume of bedload decreases. the sediment also decreases in size and the stream slows down.

Jazzie

Vertical erosion - the erosion happens downwards due to gravity. It creates steeper gradients.

Lateral erosion - widens the river as there is less gradient and the group becomes more flat.

vertical erosion: a river erodes its river bed.

lateral erosion: a river erodes its bank.

Brook

bedload increases as it moves from source to mouth. the particles siuch as rocks and pebbles decrease as you approach the river mouth becuase it loses kinetic energy required to move larger objects. Thsi results in the decreasing size of bedload matter.

Plearn

jicr26 — 2025-01-20 04:24:29 UTC

Vertical erosion erodes the riverbed vertically, causing it to become deeper while lateral erosion erodes the side of the river banks, widening the river. The first one is more common in the upper course of the river while the latter is found in the middle and lower courses.

Brook

As a river moves downstream toward its mouth, its cross-sectional area generally increases. In the upper course, near the source, the river tends to be narrower and shallower because the river is often small with a steep gradient and high-energy flow that erodes downward (vertical erosion). The flow is concentrated in a smaller area. As the river moves into the middle course, the gradient becomes gentler, and lateral erosion begins to widen the channel. This results in an increase in the cross-sectional area. In the lower course, as the river approaches the mouth, it becomes even wider and deeper due to increased lateral erosion and sediment deposition, allowing it to carry a larger volume of water.
