Document Summary
Characteristics of physiographic regions: a large contiguous area with similar landforms type, are shaped by common processes and, share a common geological history, dominant landforms. Plateaux (upland regions): flat or rolling terrain. Structures that are created from tectonic movements, (true fault lines, tectonic plates moving. Ex rocky mountains-2 faults pushing together to form mountains) Created through erosion or weathering (ex, glacial kettles, niagara falls) Sedimentary rock: compaction of sediments (organic matter) Metamorphic rock: undergone a transformation, new type, sandstone: landform process. Weathering: decomposition of rock and particles on a site (destructive) Erosion: breaking away of pieces + movement to new location. (displacement of loose material by geomorphic processes such as wind) (constructive & Deposition: deposit of material on the earth"s surface by ice, water, or wind (constructive) Faulting: the breaking of earth"s crust as a result of differential movement. Weather: atmospheric conditions at one point in time. Climate: atmospheric conditions over a long period of time.
