Suppose the stream is turning left. The water would prefer to go straight on and so it hits the right bank. This effect cuts away the right bank and deepns the bed there. Now we have the two effects. The faster water tends to go to the deeper side and so the slower water is pushed aside to the shallow left where it slows down even more.
drift
Depends on the stuff and volume
Yes it does.
Yes it does.
the answer is FASTER. so it is: Jet stream moves faster in the winter. :)
a jet stream is a narrow band of air that moves around the earth at high speeds. it is faster

Stream velocity is dependent of four things. They are, the flow type, the gradient, the channel shape, and the discharge of the stream. Streams will flow faster in narrow channels on steeper grades.
It depends on the topography of the land. Generally,however, the stream slows down as the stream moves away from the mountains.
a stream or river that has low gradient has less energy for erosion
A steep gradient will force the water to flow downhill faster.
If in a given stream the velocity doubles, the discharge: Choose one answer
For a given mass of stream water, its kinetic energy is proportional to the speed of flow squared. So, for example, if we double the speed of the stream its kinetic energy will increase by four fold. And kinetic energy can be found from the average force acting on some mass (e.g., those "particles") over a distance. So one can conclude that a faster moving stream can exert more force on the stones and debris in that stream. Which means the faster moving stream is more likely to be able to actually lift and carry larger heavier particles than the slower stream can. NOTE: This discounts particles that can float in a static stream, like wood chips, as they are carried without the stream flowing.

In a typical stream where the gradient is steep the discharge is small.
