Document Summary
Rock formation: raw material from which streams sculpt landforms. Study guide terms on page four are key for final exam. Factors that influence fluvial erosion and landscape formation. Each provides clues about their underlying geologic structures. Trellis (roots) & rectangular (four square) - ridges and valleys. Overcoming geologic structure: superimposed streams: downward eroding stream flows on surface above three buried mountain ridges, mountain crests now exposed but the stream. Landscape differences between moist and arid environments is more apparent than real. Evolution of an antecedent stream which kept flowing and eroding downward as the mountain ridge was being tectonically uplifted across its path. Part of the sediment load carried by the world"s rivers is deposited on the land as alluvium in floodplains, deltas, and elsewhere. Braided rivers (basically it looks like there is stuff in the middle of the rivers)
