What are some of the ways in which a stream carries material?
A stream carries material through processes such as erosion, transportation, and deposition. Erosion occurs when the stream’s flow dislodges and removes soil and rock from its banks and bed. The stream then transports this material in various forms: dissolved ions, suspended particles, and bedload (larger sediment that rolls or slides along the bottom). Finally, deposition happens when the stream's velocity decreases, causing it to drop its carried material, forming features like deltas and sandbars.
What is Stream bed?
A stream bed is the bottom (floor) of the stream.
What is load and how does it affect erosion?
Stream Load is the amount of material a stream can hold as it flows. As a stream flows it causes erosion, and this erosion is carried about as material in the stream. As too much is eroded, the extra material will fall to the bottom, or push it's way to the sides.
What is the name of a stream bottom?
Bed
Why do potholes form at the bottom of a stream?
Potholes form in the stream bottom through erosion caused by water and rocks and wildlife.
What determines whether a stream will erode its bottom or its sides?
it erodes on its bottom
What determines whether a stream erodes it bottom or its sides?
it erodes on its bottom
What is the difference between a stream bed and a stream bank?
A stream bed is the bottom sediment layer of the stream channel which is constantly inundated with water. It is a saturated layer of sediment inhabitated by macroinvertibrates, algae, macrophytes, and microbes. The particle size of the stream bed material (fine clay vs large rock and boulders) is dependent on geologic region, size of the stream, and stream velocity. The stream bank is the adjacent sloping walls that confine the stream on either side. They are typically not wet except in times of high flows. Banks typically can grow more terrestrial vegetation such as reeds, grasses, and trees.
What determines whether a stream erodes it bottom or it sides?
it erodes on its bottom
What is an African stream bed?
Definition of Streambed: the bottom of the stream below the usual water surface.
What is a streams bed load?
Sediment that is carried by a stream along the bottom of its channel.
What do geologists investigate if they are interested in a stream's bed load?
heavy particles that move along the bottom of the stream.
