Surface Processes I
Weathering and Erosion (Chapters 5, 18 + 19) 


Weathering 
abrasion, acid rain-1, acid rain-2,  angles of repose (example), biological effect: lichen and trees, chemical weathering,  desert varnish,  differential weathering, exfoliation (examples: Coquihalla and Half Dome), frost wedging, mechanical weathering, oxidation, regolith,  soil profile (example), soil types, spheroidal weathering, talus, ventifact, ventifact - strange 

Erosion 
alluvial fan, desert pavement, dune migration (diagram), loess

Mass Wasting
creep-fence, creep-trees, debris avalanche,  deflation, landslide, Hope Slide, rock slide, scarp, scarp - diagram, slump, solifluction or frost creep (example)
Prevention: debris flow barrier, retaining wall-1, retaining wall-2, retaining wall-3, chain-linked fencing, rock and chain, shotcrete, rock bolts, terracing,  slope stabilization methods (chart)
