Transcript of PHYSICAL GEOGRAPHY Arid Landforms
Arid Landforms
• Found in BW Climates
• Non-retentive alkaline soils
• Sparse Vegetation– Xerophytes– Succulents– Ephermals– shallow root systems
Arid Landforms
• Wind erosion & deposition
• Water erosion (most important in Arid Landforms– unprotected surface– seepage underground– intermittent rivers– exotic rivers– no ground water
Arid Landforms
• Landforms of Erosion– Badlands
– Washes, Arroyos, Wadis
– Mesas
– Buttes
– Pinnacles
• Landforms of Deposition– Bajada
– Playa
– Erg -sand dune landscapes
– Reg
– Hamada
