In which form does water rise into the atmosphere when it evaporates?
water vapor
water droplets
snow
ice
What process is happening step A?
transpiration
evaporation
condensation
accumulation
The process by which molecules of water vapor become liquid water.
transpiration
evaporation
condensation
accumulation
Any form of water that falls from clouds and reaches Earth’s surface because of gravity.
accumulation
precipitation
condensation
surface runoff
The river is at its most fast flowing
Upper Couse
Lower course

The river is at its slowest
Lower Course
Middle Course
Upper Course
a smaller river flowing into a larger river
headwaters
tributary
Every river has processes of transportation, which are
solution, suspension, corrasion and saltation
solution, suspension, saltation and attrition
solution, suspension, saltation and traction
solution, hydraulici action, corrasion and traction
Read the definition and identify it: "The process of transportation in which the lightest particles of soil and sand that make the river look cloudy as are carried along, is called .."
solution
suspension
saltation
traction
You have "traction" when
the transported minerals are dissolved in the water
smaller particles such as stoned bounce along the river bed
the heaviest particles - large stones and rocks - roll along the river bed
the lightest particles of soil and sand are carried along the river course
What are the four main processes of erosion?
Hydraulic action, abrasion, attrition and solution
Hydraulic action, corrasion, saltation and solution
Hydraulic action, abrasion, attrition and saltation
Ask Ms Daminato, I can't be bothered!
Hydraulic action is when
sand and stones rub against the bank and bed and knock off other particles
the force of the water knocks particles off the banks and the river bed
boulder and large stones carried by the river collide with each other and break into smaller pieces
when acids in the river dissolve the rocks that make up the bank and bed
What feature would you find in the lower course of a river?
Waterfall
Gorge
Meander
Delta
Where does deposition mostly occur?
Upper Course
Middle Course
Lower Course
Which river process is mostly responsible for the formation of deltas and floodplains?
Erosion
Transportation
Deposition
Build up of flat land on each side of the river that has the potential to flood.
confluence
flat plain
flood plain
watershed divide
What landforms occur in the lower course of a river?
Delta
Meander
Estuary
Levees
Natural levees are....
Man-made structures to prevent flooding
A raised bank on the edge of a flood plain
A raised bank either side of the river due to deposition
Unlevel ground on a flood plain
Rivers can be a little acidic and the acid can dissolve the rock. What is this called?
hydraulic action
corrosion
attrition
abrasion
This diagram shows the height and distance downstream from the river's source to its mouth
Gradient map
Cross profile
Cross section
Long profile
This diagram shows shows the shape of a feature or landscape as if it was cut through sideways
Long profile
Cross section
Line graph
Scattergraph
The volume of water flowing in a river at a certain point, measured in cubic metres per second (cumecs)
Velocity
Cross-sectional area
Hydraulic radius
Discharge
Here the river is eroding downwards very quickly
Upper course
Middle course
Lower course
Here there is high discharge and mainly deposition
Upper course
Middle course
Lower course
Typical characteristics of the middle course of a river:
Steep gradient
Meanders
Angular boulders
Floodplain
Downward erosion, for example of the river bed
Hydraulic action
Lateral erosion
Vertical erosion
Erosion where a river cuts sideways into its banks
Vertical erosion
Hydraulic action
Lateral erosion
This part of the river is near the coast where the river becomes salty.
meander
estuary
source
What stage of the river moves the fastest?
youthful

Where will there be the most erosion?
A
B
C
D
Where is the water in the river moving the slowest?
A
B
D
The land sitting next to the river banks which often gets covered in water when discharge is particularly high.
Levee
Delta
Floodplain
Meander
Under which of the following conditions would deposition occur in a river?
After rainfall when velocity is high
On the inside of a bend where velocity is low
During a flood when river water leaves the channel
At a river mouth when the river enters the sea
Where on a meander will erosion occur?
Inside of bend
Outside of bend
