Where does a river start?
Mouth
Source
Confluence
Tributary
What are the characteristics of the upper course of a river?
Wide, deep channel
Shallow, narrow channel
Widest, deepest channel
All of the above
Identify the characteristics of the middle course of a river.
Medium gradient, gently sloping valley sides with a wider, deeper channel.
Gentle gradient, very wide, almost flat valley, very wide and deep river channel.
Steep gradient, v-shaped valley, steep sides and narrow, shallow channel.
Where is vertical erosion the most dominant along the long profile of a river?
Upper course
Middle course
Lower course
Why is vertical erosion most dominant in the upper course of a river?
High turbulence causes the rough, angular particles transported by the river to be scraped along the riverbed, causing intense downwards erosion.
The discharge is highest here causing intense erosion.
The velocity of the water is highest here causing intense erosion.
When soluble particles are dissolved into the river it is called:
Hydraulic Action
Abrasion
Saltation
Solution
Which process involves large boulders and rocks being rolled along the river bed?
Saltation
Traction
Suspension
Solution
Which Process involves small pebbles and stones being bounced along the river bed?
Solution
Traction
Saltation
none of the above
Tiny particles such as silt are usually transported:
in solution
in suspension
by saltation
by traction
The load of the river is all the materials carried by the water
True
False
How many ways is the load transported in the river?
3
4
2
1
What is the edge of the river basin called?
waterside
waterway
watershed
water
________________ are streams that flow together to make a river.
source
tributaries
mouth
drainage basin
What river landforms are found in the upper course?
Gorge
Meander
Delta
Interlocking spurs
How do waterfalls form?
A layer of soft rock lies on top of a layer of hard rock
A layer of hard rock lies on top of a layer of hard rock
Abrasion erodes away a plunge pool at the bottom of the waterfall
Solution and traction creates a plunge pool at the bottom of the river
What type of erosion is prominent in the middle course?
Vertical erosion
Saltation
Solution
Lateral erosion
What landforms occur in the middle course of a river?
Ox-bow lakes
V-shape valleys
Flood plains
Estuary
The (a) means the fastest flow of the river
The fastest flow of the river occurs on the ____________ bend creating a _______________.
Inside
Outside
Slip-off slope
River cliff
_______________ occurs on the inside bend because the river loses its energy
deposition
transportation
erosion
