Flashies 4 Finals - Sheet1 Flashcards
Formed when weathering, together with mass collapse (and in arid areas with wind erosion), creates a tunnel through a slab of rock
Rock arch (bridge) and window
a wind erorded depression in the side of a cliff of a homogenous rock type
alcoves and yardang window
low, triangular-shaped accumulation of sediments deposited at the mouth of a valley
Alluvial Fan
Submarine, circular, steep sided holes which occur in coral reefs
Blue Hole
a compound alluvial fan where neighboring alluvial fans converge into a single apron of deposits against a slope
Bajada
Shallow lakes found in bajadas
Playas
A steep-sided and flat-topped hill, built of flat lying soft rocks capped by a more resistant layer of sedimentary rockt lava flow or duricrust, surrounded by a plaim
Butte
A deeply incised, steep-sided river valley
Canyon
asymmetrical upland feature usually associated with gently dipping
rocks and comprising a steep scarp-slope (or escaqpment) and a
longer gentler dip slope
Cuesta
A depositional landform produced by sedimentation at and around the mouth a river river- tide- wave-dominated
Delta
A large area of sand dunes
Erg
a long winding ridge of stratified sand and gravel that are frequently several km long ang are somewhat like railroad embankments
Eskers
A steep slope coinciding with the line of a fault
Fault Scarp
triangular-shaped remnants of the bedbetween V-shaped notches; steeply sloping wedge-shaped landscape features created by differential erosion
Flatirons
German ‘sea of rock’; areas covered by large angular blocks (formed in situ), traditionally believed to have been created by freeze-thaw action
Felsenmeer/Blockfield
Major splits into limestone pavement, formed by widening, deepening; and eventualnergingcofsolution features flat level” long linear weakness in the rock
Grike (Bogaz)
small closed depressions on horizontal and gently inclined rock surfces; similar to solution pits in carbonate rocks;
Gnamma
A mountaintop that has been modified by the action of ice during glaciation and frost weathering; also pyramidal peak
Glacial Horn
