What two factors determine the speed of a stream?
The gradient or slope of the streambed and the volume of water flowing through the stream are the two main factors determining the speed of a stream. A steeper gradient typically results in a faster-flowing stream, while a higher volume of water will also increase the stream's speed.
What factor is most likely to affect the amount of erosion done by a stream?
The slope or gradient of the stream is the most likely factor to affect the amount of erosion. Steeper slopes result in higher velocities, which in turn increase the erosive power of the stream. A steeper slope also allows the stream to carry larger sediment and potentially cause more erosion.
Does a stream's velocity increase or decrease downstream?
A stream's velocity typically increases downstream due to the accumulation of water volume and slope gradient. This leads to higher flow rates and faster-moving water.
Diffusion can be accelerated by?
Increasing the temperature, lighter particles, higher surface area to volume ratio and a steeper concentration gradient.
What does a stream's ability to erode mainly depend on?
The amount of water in the stream and the gradient. However if you had two streams both with the same amount of water in them but with one stream flowing down a steeper slope (gradient) than the other, then the steep one has more ability to erode.
How do gradient and discharge change?
Gradient refers to the steepness or slope of a river or stream, affecting its velocity. As gradient decreases, discharge typically increases because the water spreads out over a larger area, allowing for higher flow volumes. Conversely, in steeper areas, higher gradients can lead to faster flow but lower discharge due to limited water volume. Therefore, the relationship between gradient and discharge is often inversely proportional in river systems.
Why might a stream volume increase or decrease?
pressure, temperature, possibly somethign else
Why does urine volume decrease as the gradient concentration increases?
As the concentration gradient increases, more water is reabsorbed by the kidneys, leading to concentrated urine with lower volume. This allows the body to conserve water and maintain proper electrolyte balance.
What factors determine velocity of stream?
Speed and direction determine velocity
What is the result of intrapulmonary volume increase?
An increase in intrapulmonary volume leads to a decrease in air pressure within the lungs. This decrease in pressure creates a pressure gradient, causing air to flow into the lungs during inhalation.
What Controls the maximum size particle a stream can carry?
The maximum size particle a stream can carry is primarily controlled by the stream's velocity and discharge, which is the volume of water flowing per unit of time. Faster-moving water can transport larger and heavier particles due to increased kinetic energy. Additionally, the stream's gradient and channel shape can influence sediment transport, with steeper gradients typically facilitating the movement of larger particles. Lastly, the sediment's shape and density also play a role in determining its transport capacity.
What change will a pebble usually undergo when it is transported a great distance by stream?
It will become rounded and it's volume will decrease.
