7. 1. Erosional Processes

9. Hydraulic Action
• The sheer _______ of water hitting the bed
and banks. Most effective when ______
volumes of water are moving ______.
a) Weight small fast
b) Force large fast
c) Power bigger forward

10. Abrasion
• The ______ in the river repeatedly hits the
river bed and banks, causing __________ to
break off.
a) Load material
b) Rocks china
c) Water banks

11. Solution
• When the _______ flows over certain types
of rock, such as chalk and limestone, the rock
__________in the water.
a) Steam repels
b) River dissolves
c) Water disappears

12. Attrition
• ______ and boulders knock against each
other, over time pieces fall off and the
particles reduce in ______.
a) Water size
b) Stones size
c) People size

13. 2. Transportation

15. Traction
• __________ rocks and other large pieces of
sediment along the ______ bed
a) Floating sea
b) Trundling bunk
c) Rolling river

16. Saltation
• ________ pieces of sediment or sands are
___________ along the river bed
a) Fine bulldozed
b) Small bounced
c) Large bounced

17. Suspension
• Very small particles such as ________ or sands
are carried in the water. This gives the water a
___________ look.
a) Clays cloudy
b) Stones dirty
c) Granite cute

18. Solution
• Some ___________ can become
____________ into the river. This requires the
least energy.
a) Minerals dissolved
b) People engulfed
c) Streams tributaries

19. 3. Deposition

20. Ganges Delta

22. 4. Deposition

23. Deposition
• This is when a river ______ the load it is
carrying when its energy levels drop. This
happens when there is a drop in the river’s
v_______or a drop in the v______of water
flowing.
• Normally the bigger, ________particles are
deposited first, whilst smaller particles are
dropped last. Deposition often occurs at the
_______of a river as it flows into a lake or sea.

24. 4. Mass Movement

26. Soil Creep

27. Soil Creep
• When particles of soil _________move down
the slopes (towards a ________)

28. Sliding (e.g. landslide)

29. Sliding
• When material moves downslope in one ____,
e.g. a ___________. This could be caused by
undercutting from erosion at the bottom of
the _____ .

30. Flows

31. Flows
• Soil, often mixed with water, flow like ______
downhill _____.

32. 5. Weathering
What can you remember from
coasts?

33. Mechanical

34. Chemical

35. Biological

36. Homework
• Using the processes of a river (erosion, transportation or
deposition) produce a poem or a recipe or a story about
that process!
Example poem:
Erosion wears the river banks away,
The rocks are so brittle they easily
fray.
Always flowing and carrying the
load,
Hydraulic action causes the rocks to
almost explode!
Example recipe:
Ingredients: ………….
Erosion: Take soluble
minerals as river flows and
dissolve them to make
solution
Transportation: Pick up a
handful of rocks and throw
them so they skip along the
river bed

37. You say we pay

• Hydraulic Action

39. Homework
• Choose one process (not deposition) and find
photographs that show the different types of
that process.
• Print them off and label them in your exercise
book.
