Question

questions: 1. what happens when you first add water to the stream table? does a stream form immediately? if so, how does the water flow? if not, describe what happens instead. 2. when the stream forms, does it flow in a straight line? 3. what determines the path of the stream? 4. illustrate or describe your trials from the investigation. where does erosion occur along the stream? where does deposition occur? does this vary depending on the changes you made during the investigation?

Explanation:

1. When water is first added to the stream table, it may not form a stream immediately. Instead, it might pool in low - lying areas or spread out slowly depending on the surface texture and slope of the table. If a stream does form right away, the water will flow downhill due to gravity, following the path of least resistance.
2. When the stream forms, it usually does not flow in a straight line. Natural irregularities in the stream table's surface, such as bumps or depressions, cause the water to meander.
3. The path of the stream is determined by factors like the slope of the table surface, the presence of obstacles (like rocks or raised areas), and the initial distribution of water. Steeper slopes will cause faster - flowing streams, and obstacles can divert the water's path.
4. Erosion typically occurs on the outer banks of meanders in the stream where the water flow is faster and has more energy to wear away the sediment. Deposition occurs on the inner banks of meanders where the water flow is slower and sediment drops out. These locations can vary depending on changes made during the investigation, such as altering the slope, adding or removing obstacles, or changing the water flow rate.

Answer:

1. Water may pool or spread slowly; if a stream forms, it flows downhill by gravity.
2. No, it usually does not flow in a straight line.
3. Slope, obstacles, and initial water distribution.
4. Erosion on outer meander banks, deposition on inner meander banks; can vary with investigation changes.
