River Processes And Courses Flashcards
What is deposition?
When something is dropped what it was carrying.
What is erosion?
It is wearing away land or collecting and destroying land.
What is transportation?
It is moving something to another place and it is the movement of rocks and sediment.
What course are there most erosions that are common and why?
The upper course is most common with erosions because it is a bigger slope and the water would move faster.
What is the main process of the upper course?
The main process if erosion.
What is the main process of the middle course?
The main process of the middle course are the erosion and deposition .
What is the main process of the lower course?
The main process of the lower course is the deposition because the river loses energy.
What happens to the upper course when there is a river valley?
The upper course becomes a v shaped valley and it erodes downwards .
What happens to the middle course in the river valley?
The middle course has banks that are eroded and the channel would get wider. There would be a flood plain and the river would get flooded.
What happens to the lower course in the river valley?
In the lower course there is a wide channel and it is deeper. There is more water that is held and there is a wider flood plain.
