What could cause a stream to deposit the sediment?
A decrease in stream velocity due to factors such as a decrease in slope or widening of the stream channel can cause sediment to be deposited. When the stream's capacity to transport sediment is exceeded, it drops the sediment it was carrying. Additionally, changes in the stream's flow rate or turbulence levels can also result in sediment deposition.
If tectonic forces uplift the crust beneath a stream drainage and steepen the gradient of the stream drainage area what is the response of the stream?
The stream will begin to downcut, eroding the bedrock as it tries to establish a new equilibrium with the steeper gradient. The increased energy from the steeper gradient will cause the stream to transport sediment more efficiently downstream. Over time, the stream will adjust its profile by eroding its bed and banks to accommodate the new uplifted crust.
Describe how the Gulf Stream produces milder winters in Scandinavia?
As this stream travels north, it transfers heat and moisture from its warm waters to the air above. Westerly winds carry the warm air to the British Isles and to Scandinavia. The westerly winds cause these places to have milder winters than they would otherwise experience at their northern latitudes.
What effect can flooding have on a stream?
Flooding can cause erosion of stream banks, change the stream channel morphology, alter water quality by carrying pollutants, and disrupt aquatic habitats by displacing or killing organisms.
How can sediment transported in a stream cause abrasion?
Sediment transported in a stream can cause abrasion by acting as a kind of sandpaper, physically rubbing against and wearing away the surface of rocks and other materials in the stream's bed and banks. The force of the moving water and sediment can increase the rate of abrasion, particularly in areas with high sediment loads or fast-flowing currents. Over time, this abrasion can result in the erosion and shaping of the stream's channel.
Would raising the base level cause a stream to gain energy and erode?
Yes, raising the base level of a stream can lead to an increase in energy, causing the stream to erode its banks and bed. When the base level rises, the stream's gradient decreases, which can result in a higher flow velocity upstream. This increased energy can lead to enhanced erosion as the stream works to adjust to the new base level. However, the extent of erosion will depend on factors such as sediment supply, vegetation, and local geology.
What would lowering a stream's base level will cause the stream to do?
Lowering a stream's base level will cause the stream to do what?
What happens when the speed of a stream increases?
Things that would cause a stream to move faster would be how large the stream is, how much material is in the stream and how much of a slope the stream is at. Things blocking the stream would also cause it to move slower.
Would cause a decrease in the supply of money?
raising of interest rates
What change in the stream would cause pebbles to be deposited farther offshore?
A greater volume of water would cause this.
What will lowering a streams base level cause the stream to do?
Lowering a stream's base level will cause the stream to do what?
What would cause an increase in aggregate demand in the short run?
if decrease a price or if the expectation of raising a price
How might you have a contributory role in raising money for good cause?
You might have a contributory role in raising money for a good cause by going out and raising money on the streets or going door to door.
Lowering a stream's base level will cause the stream to?
If you lower a stream base level it will cause a down cut. In some cases this is a good thing.
What kind of stream bed would cause the most friction?
A rocky stream bed with large, irregularly shaped rocks would cause the most friction for water flowing over it. The rough surface of the rocks creates turbulence and resistance, slowing down the water flow.
How can a stream cause erosion?
Little sediments are carried by the eroding stream
What would cause a streams discharge to increase?
An increase in precipitation, snowmelt, or glacial melt can cause a stream's discharge to increase. Additionally, if there is a sudden influx of water from a tributary or a dam release upstream, it can also lead to an increase in stream discharge.
