1

The path of a river as it flows downhill is called its

Course

2

Where is the upper course closest to?

Source of the river

3

Where is the lower course closest to?

Mouth of the river

4

What do rivers form when they flow downhill?

Channels
Valleys

5

The shape of the valley and channel changes due to what?

Erosion
Deposition

6

What does the long profile show?

The gradient changes over the course of the river

7

What does the cross profile show?

Shows you what a cross-section of the river looks like

8

Describe the upper course

V-shaped valley
Steep sides
Narrow
Shallow channel

9

Describe the middle course

Gently sloping valley sides
Wider
Deeper channel

10

Describe the lower course?

Very wide
Almost flat valley
Deep channel

11

What changes the cross profile of a river?

Vertical and Lateral erosion

12

What happens when Vertical erosion takes place?

Deepens the valley and channel
Making it V-Shaped

13

Where is vertical erosion most dominant?

Upper course of the river

14

What happens when Lateral erosion takes place?

It widens the valley and channel.

15

Where is lateral erosion most dominant?

Middle and lower courses.

16

What does the flowing of the water do to the landscape?

It erodes the landscape.
Wears it down.
Then transports the material somewhere else where its deposited.
