Why does bed load decrease in size?
The bedload becomes smaller when the river is flowing downstream, and the rocks also become smaller, smoother and rounder due to attrition and abrasion. (The reason the flow slows down is because the energy of the flow decreases.)
What is the definition of undissected plateau?
The best answer I can find is:"a relatively flat surface that has not been cut by a river."
Where is one most likely to find rocks that have become smooth and rounded?
River beds.
Where can you find waterfalls ex. mountains....?
You can usually find waterfalls wherever land has been uplifted and the erosional effects of a stream or river has yet to cut down to a more gradual gradient.
How does the speed of a river help determine what type of material the river carries?
The speed of a river determines on the age of the river. The younger the river the faster and stronger the river is, the older the river the slower and weaker the river is.
What is a bedload?
waste transported from the river!
What is river efficiency?
River efficiency is how easily a river can move water, sediment and bedload.
The amount of sediment that a river carries is its?
bedload
What is bedload in a river channel?
It is sediment transported by a river that becomes too heavy to be in suspension and thus sinks
How do natural levees form?
Banks of coarse river load and other material that has been transported down river, that are made when the river floods and bedload is carried out wider then before and desposited. It is left with the river recedes creating a higher banks
Is the ocean the same depth everywhere?
No, it can be affected by things such as the bedload of the river and the width.
How do you calculate bedload size?
You cannot:)
Why why does bed load change as it goes downstream?
The size of the pebble will decrease down stream because the further downstream you go the quicker the river velocity. This means there will be more abrasion against the sides and bed of the river and the friction will be greater, this wears away the river load making it decrease in size. Increase velocity means that bigger material will be picked up by the river and carried as river load. More load in the river and increased size of load will mean more attrition and the river load will keep colliding into each other smoothening and rounding their shape. Brap brap !!
What landforms do the upper course of the river have?
V-shaped valleys The river channel - vertical erosion, shallow but a very fast flow Waterfalls Gorges(which are formed by waterfalls) Bedload is also very big and angular.
Does the rivers velocity affect the rivers bed load shape and size?
Faster river velocities are capable of carrying greater amounts of bedload and transporting them farther and faster. The shape of the sediments of the bedload would therefore be exposed to more physical weathering which would progressively round the sediments and also decrease their size.
What is the fine sediment transported within the body of flowing water?
a bedload
Why does the Bedload size become smaller and more rounded as you go downstream?
