The competence of a stream shows the maximum single load i.e. individual large rock, that the stream can move. It ignores the rest of the load in the river. The capacity would include the rest of the finer load so it is the whole load of the stream (including the large rock) Thus capacity will always be more than competence.
What else can I help you with?
Is a jet stream faster or slower in the winter?
The jet stream is typically faster in the winter due to greater temperature contrasts between polar and tropical regions. This temperature difference creates stronger winds that drive the jet stream at higher speeds during the winter months.
What winds control the jet stream?
Wind doesn't control the jet stream; this is controlled by something much more complex. It has to do with the mass balance of the atmosphere, vertically propagating waves, and the earth's rotation.
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.
Why does jet stream move faster in the winter?
The temperature difference between the cold polar regions and the warmer lower latitudes increases in the winter, intensifying the pressure gradient and causing the jet stream to move faster. Additionally, shorter days and longer nights in the winter result in a more pronounced temperature gradient, further accelerating the jet stream.
What statement is true of jet streams A. The subtropical jet stream lies between the westerlies and polar easterlies. B. The subtropical jet stream flows to the east while the polar jet stream flows?
A. The subtropical jet stream lies between the westerlies and polar easterlies; this statement is true. B. The polar jet stream typically flows to the east, while the subtropical jet stream flows towards the west.
How does a river's velocity affect its competence and capacity?
the competence and capacity of a steam depend on a streams velocity and discharge. Because the velocity and discharge of a given stream are not constant , the competence and capacity of a stream are not constant . competence and capacity vary along a stream and change throughout the year.
What stream characteristic is measured by the size of the largest particle that a stream can move?
The measure of the largest particles a stream can carry is capacity.
What factor determines the competence of a stream?
The competence of a stream is determined by the stream's velocity and the size of the sediment it can transport. Streams with higher velocities and larger sediment sizes are typically more competent and can transport larger particles.
What is the relationship between the carrying capacity of a stream and it and discharge and velocity?
The carrying capacity of a stream refers to its ability to transport sediment. Higher discharge and velocity typically increase a stream's carrying capacity as they provide more energy to move sediment. However, if the stream's carrying capacity surpasses its available sediment, deposition can occur.
If a stream's discharge decreases how does it affect the stream's capacity?
The capacity of a stream is the maximum load it can carry. Capacity is directly related to a stream's discharge. The greater the volume of water in a stream is, the greater its capacity is for carrying sediment. So if a stream's discharge decreases, the stream's capacity also decreases.
What factor controls the competence of a stream?
Competence depends mainly on flow speed, with the power of the water generally increasing by the square of its speed.
What is the relationship between the carrying capacity of a stream and its discharge and velocity?
The carrying capacity of a stream is influenced by its discharge and velocity. Higher discharge and faster velocity can increase the stream's ability to transport sediment and debris, thus raising its carrying capacity. Conversely, lower discharge and slower velocity may result in a reduced carrying capacity as the stream has less energy to move material.
What is the relationship between the carrying capacity of a stream and it's discharge and velocity?
The carrying capacity of a stream is influenced by its discharge and velocity. A higher discharge and velocity typically allow a stream to transport larger sediments and materials downstream, increasing its carrying capacity. Conversely, lower discharge and velocity may limit the stream's ability to carry sediment and materials.
How does the velocity of a stream effect its carring capacity?
The higher the velocity of the stream the larger carrying capacity it has.
How do the competence and capacity of a small fast-flowing stream in the Rocky Mountains compare with the lower part of the Mississippi river?
The competence and capacity of a small fast-flowing stream in the Rocky Mountains are generally lower than those of the lower part of the Mississippi River. The small stream can transport smaller sediment particles due to its higher velocity, but its overall discharge and ability to carry larger sediment loads are limited compared to the vast, meandering Mississippi. In contrast, the lower Mississippi has a much greater volume of water, allowing it to transport larger sediments and maintain a higher capacity for sediment transport over longer distances. Thus, while both waterways can move sediment, their scale and effectiveness differ significantly.
What is the relationship between the carrying of the thr what is the relationship between the carrying capacity of a stream and its discharge and velocity?
The carrying capacity of a stream refers to the maximum amount of sediment and material it can transport, which is influenced by its discharge and velocity. Higher discharge increases the volume of water flow, allowing the stream to carry more sediment. Similarly, greater velocity enhances the stream's ability to lift and carry particles, increasing its overall carrying capacity. Therefore, both discharge and velocity are critical factors that determine how much material a stream can transport.
What is the difference between a continental jet stream and a polar jet stream?
A continental jet-stream travels parallel to the equator - a polar jet-stream travels in a north/south direction.
