13. SORTING OF
SEDIMENTS:
Horizontal Sorting:
a gradual change in the
size,shape and density
(of deposited particles)
when a stream slows down

14. Horizontal Sorting
boulders
cobbles
Roundest pebbles
and sand
densest
Precipitation
……………
silt
…………….
Ions in
…………….
(colloids)
clay …………….
solution
Smallest
flattest
least dense

18. Graded Bedding:
Each layer
represents
a single
event of
deposition
Largest
at
bottom
smallest
at top

19. EROSIONAL
-DEPOSITIONAL
SYSTEM:
___________ or
___________ are examples
of this kind of system.

20. Within a stream system
energy transforms from
____________
to ____________
energy.

21. Erosion
_____________
_Will dominate in
the steeper
section and

23. Deposition
______________
In places of less
gradient
or slope.

25. Kinetic Energy
depends on
Slope-
__________________
velocity increases
Kinetic energy increases
more erosion occurs

28. Potential Energy
depends
height
on__________
not Slope
energy is stored and
deposition occurs

29. When the rate of
erosion equals rate of
deposition:
Dynamic Equilibrium
___________________
is reached
