LANDSCAPE EVOLUTION (?)

• How Do We Recognize Landforms?
• topography
• elevation
• relief

• erosion and sedimentation

• Factors that form Landscapes: Thought 1
• climate - shorelines, glaciers, wind and deserts
• latitude
• differential erosion - especially in arid regions

tectonics - uplift and erosion relationship

• Factors that form Landscapes: Thought 2
• internal heat engine - tectonics
• external heat engine - climate

• Landforms created by the processes above
• mountains and hills
• plateaus and mesas

• cuestas, hogbacks and flatirons
• stable platforms
• folded mountain belts

• Evolution of Thought Toward Landscape Evolution
• Davis Cycle-3 Stages of Landform Development
• youthful
• maturity
• old age

• Current Thought
• tectonism causes uplift
• isostasy
• climate modifies
