types of landforms
coastal, fluvial, pedological, glacial, mass wasting, eolian, tectonics, and humans
examples of coastal landforms
beaches, marshes, swamps, deltas, platforms, terraces
examples of fluvial landforms
point bars, cut bank, flood plains, terrace, delta
examples of pedological landforms
soils, paleosols, geosols, catenas, fragipans
examples of mass wasting landforms
slumps, slides, falls, scarps, fans, debris flow
examples of eolian landforms
dunes, loess, ventifacts
what is loess
windblown silt that implies its glacially ground up “stuff”
examples of tectonic landforms
flat irons, scarps, plateaus, pediments
examples of human landforms
anything w straight lines, piles of debris
what are ventifacts
sand blasted by wind
what are flat irons
mountains go up and expose rooks, and then the streams erode it away into a triangle shape
what are the agents of change
gravity, river and oceans, glaciers, wind, and humans
what is the primary agent of change
gravity
how do rivers and oceans act as agents of change
waves, tides and sea levels; river fluctuations
what influences river fluctuations
climate determines how much water is in the system
how do glaciers and rivers act as agents of change
meandering rivers, glacial moraines
how do rivers act as agents of change
river down cuts and creates terraces when the climate changes; they move across the valley before glaciers advance
how does wind act as an agent of change
dunes that can be made of sand, silt, or clay
dunes do not equate to what? and why?
wind, the term dune refers to the shape
how do humans act as agents of change
by removing or oversteeping slopes that cause mass wasting, dam failure, building buildings on cliffs, coastal construction
