16 and 22- Mass Wasting, Weathering, Erosion, Landscape (T3)

The maximum angle at which a slope of loose material can lie without sliding downhill.

Sediment that is compacted and bound together by mineral cements.

A slow downhill mass movement of soil or other debris at a rate ranging from about 1 to 10 mm/year.

A physical weathering process in which large flat or curved sheets of rock are detached from an outcrop.

A physical weathering process in which the expansion of freezing water in cracks in rock breaks the rock.

An organic component of soil consisting of the remains and waste products of the many organisms living in that soil.

A white to cream-colored clay produced by the weathering of feldspar.

The temporary transformation of solid material to a fluid state when it is saturated with water.

All the processes by which weathered and unweathered Earth materials move downslope in large amounts and in large single events, usually under the influence of gravity.

A slow mass movement of unconsolidated material that travels as a unit.

An intricate combination of weathered rock and organic material.

Large blocks of broken rock that fall from a steep cliff of limestone or hard, cemented sandstone and accumulate in a gentler slope at the foot of the cliff.

Sediment that is loose and uncemented.

A fluid or hardened stream or avalanche of mud.

Geological phenomena in which water-laden masses of soil and fragmented rock rush down mountainsides, funnel into stream channels, entrain objects in their paths, and form thick, muddy deposits on valley floors.
