Which earth materials are deposited first as the water in a river slows down?
Larger particles are deposited first as a stream loses velocity. Gravel would be deposited first, since it is the largest (out of Clay, Silt, Sand, and Gravel)
What is alluvial deposition?
Alluvial sediment:is clay or silt or gravel carried by rushing streams and deposited where the stream slows down. Alluvial deposition refers to this process.by which alluvium is thus deposited.
What stream load has gravel and rocks?
Most likely a fast moving stream.
When is a stream likely to meander?
All streams meander to some extent. The most likely time is when flow is consistent and gradient is uniform. See Braided Stream. When a stream has eroded the steep valleys to genteler slopes, the stream flows more slowly.Now water in the stream erodes along the sides of the stream bed rather than along the stream bottom. === ===
What is an Eskers?
They are formed by streams that deposited minerals that flowed on top of glaciers, inside the cracks of glaciers, and in tunnels below glaciers
Which sedimentary rock is most likely to have been deposited in very high-energy stream?
conglomerate

What is stream deposition?
A stream's sediment load is typically deposited, eroded, and redeposited many times in a stream channel, especially during climatic variations such as flooding. Sediments are deposited throughout the length of the stream as bars or floodplain deposits. At the mouth of the stream, the sediments are usually deposited in alluvial fans or deltas, which represent a lower-energy, more "permanent" depositional environment that is less susceptible to changes in the stream flow. i got this from clift notes
Which change at a particular location in a stream usually causes more sediments to be deposited at a location?
Decrease in stream velocity
Which change at a particular locating in a stream usually causes more sediment to be deposited at that location?
Decrease in stream velocity

Decrease in stream velocity
In a stream channel what sediment is deposited first?
gravel sized particles
How could you distinguish a layer of sedimentary rock created close to the head of a stream from one created near the stream's mouth?
The sedimentary rock from the stream mouth will contain more marine fossils (i.e. any at all) and will be composed of finer grains (as they are eroded during passage in the stream and as the stream gets closer to the sea or a lake it will tend to become wider and have a lower flow velocity meaning it has less energy to transport sediment meaning that the larger particles will have been deposited further up the stream nearer it's head). The rock from the stream head will have coarser grains and a lack of any marine fossils. Other indicators may be used depending on the specific rock type.
A lode is a layer of minerals that has been deposited in a stream bed True or False?
This is false. A lode is not a layer of minerals that has been deposited in a stream. A lode is formed by hot mineral solutions going into the cracks of the rocks.
Pile of sand or gravel deposited by a stream inside the meander?
Levees and regoliths.
What is the general term for any well sorted stream-deposited sediment?
Sedimentation.
