breccia c loess d rock flour e desert pavement 21 The region of a desert landscape marked by high relief sparse or absent vegetation and little or no soil is the a arid zone b bajada c zone of erosion d zone of deposition e playa 22 Deserts tend to have high relief with abundant steep slopes and cliffs because a the wind is very strong b the land is rising c there is little vegetation to prevent water erosion d deserts are tectonically active e there is no rain 23 The black manganese oxide coating that commonly forms on vertical rock surfaces in deserts is called a desert pavement b desert varnish c petroglyphs d rock flour e loess 24 Deserts tend to occur in regions that are characterized by a tropical latitudes b ascending air masses c descending air masses d high winds e abundant sand 25 Any large permanent non seasonal mass of ice that is formed on land and moves under the force of gravity is a a snowfield b crevasse c icefall d glacier e avalanche 26 The line dividing the zone of accumulation from the zone of wastage ablation on a valley glacier is called the a snow line b bergschrund c cirque d drumlin e terminal moraine 27 Tensional fractures in the surface of a glacier are called a ar tes b bergschrunds c crevasses d drumlins e seracs 28 Compressional waves on the surface of a glacier are called a avalanches b bergschrunds c ogives d crevasses e seracs 29 A ridge of till down the center of a glacier is called a n a lateral moraine b end moraine c medial moraine d drumlin 30 A narrow knife edge ridge connecting two peaks in glacier eroded mountains is a n a ar te b bergschrund c cirque d crevasse e ogive e esker 31 Wind deposited silt sized particles of glacial rock flour can form significant deposits in periglacial regions This material is called a karst b till c loess d moraine e breccia 32 An asymmetric ridge in dipping sedimentary layers such as the Flatirons is known as a a hogback b mesa c plateau d flatiron e cuesta 33 Valleys eroded by fast moving high gradient mountain streams have a characteristic a V shape b U shape c flat bottom d broad flood plain e meander pattern 34 A low relief coastline with barrier islands lagoons and
