Mass Wasting
The two main factors that create a mass wasting event
What are Gravity and Saturated soil?
The total area drained by a stream and its tributaries
What is a Drainage Basin?
The percentage of Earth's freshwater that is underground
What is 30.1%?
A desert formed downwind of where moist air rises over high mountain streams
What is a Rain Shadow Desert?
An area centered around the four corners area that is significantly higher in elevation and stops at the Basin and Range province
What is the Colorado Plateau?
The slowest form of Mass Wasting
What is a Creep?
Three types of drainage patterns
What are Dendritic, Radial, and Trellis?
The top of the zone of saturation where groundwater collects
What is the Water Table?
Three characteristics of deserts
What are Intermittent Stream Beds, Flash Floods, and Steep-Sided Canyons?
What forms when a well drains water from the water table extremely fast
What is a Cone of Depression?
Part of a slump that, if removed, will cause another failure
What is a Toe?
The formation formed on the outer edge of a stream's meander
What is a Cut Bank?
The capacity of a rock to transmit fluids through pores and fractures
That is Permeability?
A rock that has been eroded by wind
What is a Ventifact?
A place where water flows naturally from rock or sediment onto the ground surface
What is a Spring?
An angle that all loose sediment will settle into as the most stable form
What is the Angle of Repose?
Broad strips of land created by sedimentation on either side of a stream channel
What is a Floodplain?
Rock/sediment tat retards groundwater flow due to low porosity or permeability
What is an Aquitard?
The side of a sand dune that sand blown by the wind falls on, creating layers
What is a Slip Face?
A buildup of sediment alongside a stream channel that keeps the stream inside of it
What is a Levee?
A fan-shaped feature that forms at the mouth of canyons
What is an Alluvial Fan?
The process of deepening a valley by erosion of the streambed
What is Downcutting?
An area with rolling hills, disappearing streams, and sinkholes
What is Karst topography?
A type of storm that occurs if high-speed winds pick up fine-grained sediments into the air
What is a Dust Storm/Haboob?
What is a scarp?
