Weather
Height
Deforestation
Erosion occurs on the _________ bend of meanders.
outer
inner
lateral
vertical
A gorge is formed by...
a waterfall retreating
a meander moving
a levee forming
a flood occurring
What do we call any type of water falling from the sky?

Infiltration
Surface run-off
Evaporation
What do we call water entering the ground?
Precipitation
Infiltration
Surface run-off
Evaporation
V-shaped valleys are formed by which type of weathering?
Chemical weathering
Freeze-thaw weathering
Salt weathering
How is relief shown on a map?
Lines of latitude
Grid references
Lines of best fit
Contour lines
A gorge is characterised by...
very steep sides
a very deep bed
very wide banks
a v-shape valley
Freeze-thaw weathering is caused by: (2)
cold highland temperatures
high levels of relief rainfall
strong vertical erosion
Very steep slopes
Which process of erosion does not wear away the bed and banks of the river?
Attrition
Abrasion
Solution
Hydraulic power
Why do waterfalls retreat?
Hard rock is undercut and collapses
Plunge pools become too deep
The river slowly erodes the hard rock
Soft rock is very resistant to erosion
Which areas of the UK are most mountainous?
South and east
South and west
North and east
North and west
Which type of rock is extremely resistant due to it being formed under heat and pressure?
Igneous
Metamorphic
Sedimentary
Glacial moraine
What do we call the divide between drainage basins?
A watershed
A confluence
A tributary
A catchment area
What do we call it when rocks are broken down in situ?
Weathering
Erosion
Deposition
Transportation
Which processes form a v-shaped valley?

What features do we find in the upper course?
Waterfalls
Interlocking spurs
Meanders
Floodplains
What is discharge measured in?
metres per second
cubic metres per second
liters per kilometer
miles per hour
Why does lateral erosion dominate the middle course?
Steep gradient
Shallow gradient
High discharge
Low discharge
Why does vertical erosion dominate the upper course?
Steep gradient
Shallow gradient
High discharge
Low discharge
What features are found in the lower course?
Waterfalls
Meanders
Flood plains and levees
Estuaries
Why are natural levees formed? (2)
Flooding transports sediment over the banks
Heavier sediment is harder to transport
In order to help protect areas from flooding
They are a form of hard engineering
What does deposition form on the inner bank of a meander?
A slip-off slope
A river cliff
A plunge pool
A gorge
What causes the river velocity to be higher on the outer bank of a meander?
The river's momentum
The amount of sediment
The river discharge
A lack of energy
In which direction do meanders move?
Towards the outer bank
Towards the inner bank
What are the characteristics of estuaries? (3)
Very wide and deep
High levels of deposition
Lots of wildlife
Fast-moving water
