GCSE Geography: River landscapes (video)
Fluvial processes and landforms — erosion, transport, deposition and the changing river course — from tutor2u. Each card deep-links to the video.
What is a tributary?
show the answer
A small stream feeding into the main river channel.
What is a drainage basin?
show the answer
The area of land that is drained by one river and its tributaries. Also known as the catchment area.
What is a confluence?

What is the watershed in river geography?
show the answer

show the answer
The force of water hitting the riverbank and squeezing air into cracks in the rocks, weakening them from the inside.
What is abrasion in river erosion?
show the answer
The force of sediment and rocks in the water scratching and scraping away at the riverbank and bed.
What is attrition?
show the answer
The process of rocks hitting each other and breaking into smaller rocks as they're transported along.
In river transportation, what is traction?
show the answer
The process where heavy rocks and boulders are rolled along the riverbed.
In river transportation, what is saltation?
show the answer
The process where small stones and pebbles bounce along the riverbed.
What type of erosion is dominant in the upper course of a river?
show the answer
Vertical erosion, which creates steep-sided V-shaped valleys.
What is discharge in river geography?
show the answer
The volume of water passing through a river at a given point.
How do plant roots help reduce river erosion?
show the answer
The roots bind the soil together, providing reinforcement and stabilizing the slope.
