The River Valley quiz - GCSE AQA Geography

Which is the definition of a river's upper course?

Which is the definition of a river's lower course?

The [blank_start]shape[blank_end] of the [blank_start]valley[blank_end] changes along the river. The shape depends on which is the [blank_start]dominant[blank_end] process - erosion or [blank_start]deposition[blank_end].

The cross profile shows the gradient of the river over different courses.

The cross profile is the cross section of the river and shows the shape of the valley and the channels as the river changes over the courses.

[blank_start]Vertical erosion[blank_end] deepens the river valley and channel, making it v-shaped.

Vertical erosion is dominant in the lower course.

[blank_start]Lateral[blank_end] erosion [blank_start]widens[blank_end] the river valley and channel.

A dominant process is one that has the most impact.

Define 'river course'.
