1. Aquatic Landscapes/The
Hydrosphere
-External processes in rock cycle
-Mass wasting vs Erosion
-Water cycle
-Stream velocity
-Stream base level and erosion

2. External processes
Weathering
Mass Wasting Solar Powered
Erosion

5. Weathering
Disintegration and decomposition of rock at or
near the Earth’s surface

12. Mass Wasting
Transfer of rock material down-slope under the
influence of gravity

13. Creep

16. Rockslide

18. Slump

20. Erosion
Incorporation and transportation of material by
a mobile agent, usually water, wind or ice

27. Transfer Mechanisms
Evaporation:
-liquid substance becomes a gas.
-When water is heated, it evaporates.
-The molecules move and vibrate so quickly that they
escape into the atmosphere as molecules of water vapor.

28. Evapotranspiration:
the sum of evaporation
and plant transpiration from
the Earth's land and ocean
surface to the atmosphere

29. Precipitation
Precipitation is water released from clouds in
the form of rain, freezing rain, sleet, snow, or
hail.

31. Infiltration

33. STRREEEAAMAMMASSS
Streamflow:
velocity; usually
greatest in the middle
-least friction
Changes in a bend

34. Gradient

35. Discharge
Volume of water moving down a stream per
unit of time

41. Stream Transportation
Dissolved Load: in solution
>Contribution by groundwater
>Chemicals, minerals, nutrients
Suspended Load: Floating,
>sediment, particles, silt, sand, clay...
Bed Load:
>rolling and scooting along the bottom

42. Capacity Vs Competence
Capacity: the amount of stuff the stream can
carry/move (>discarge = >capacity)
Competence: biggest stuff the stream can
move (>streamflow = >competence)
