Rivers Profiles Flashcards
1
Q
Course
A
Path of river as it flows downhill
2
Q
Long profile
A
Shows the gradient change of the river
3
Q
Uppercourse
A
- Steep gradient
- V-shaped valley, steep sides
- Narrow & shallow channels
4
Q
Middle course
A
- Medium gradient
- Wide & deep channel
- Wide flat U-shaped valleys
5
Q
Lower course
A
- Gentle gradient
- Very wide and deep channel
6
Q
Upper course process
A
- Erosion
- Fast water flow
- V-shaped valley
7
Q
Middle course process
A
- Transportation
- Water speed slows
- Meanders and Oxbows
8
Q
Lower course process
A
- Deposition
- Water speed very slow
9
Q
What are the 2 type of erosions
A
Vertical and lateral erosion
10
Q
Where does vertical erosion take place?
A
Uppercourse
11
Q
Where does lateral erosion take place?
A
Lower course
12
Q
Vertical erosion
A
Due to the gradient being steep, the river flows quickly and cause the channel to form a V-shaped valley
13
Q
Lateral erosion
A
Due to the gradient being more gentle, the speed of the water flow is more slow and causes the river to erode horizontally
