EVSC 2800: Interlude F

landscape

overall shape and character of land surface in a region

landform

particular land surface shape

uplift

upward vertical movement of earth’s surface

subsidence

vertical sinking of earth’s surface

relief

difference in elevation between adjacent high and low regions

downslope movement

tumbling/sliding of rock and sediment from higher elevevations to lower ones

erosion

grinding away and removal of substrate by moving water/air/ice

deposition

process by which sediment settles out of transporting medium

topographic profile

trace of surface on vertical plane sliced into ground

geologic cross section

topographic profile with geologic features

erosional landform

landform that results from breakdown and removal of rock or sediment

agent of erosion

ice, water, air

depositional landform

landform resulting from deposition of sediment where medium carrying sediment evaporates/slows down/melts

hydrosphere

earth’s water (atmo, surface, frozen, subsurface)

hydrologic cycle

continual passage of water from one reservoir to another

residence time

average length of time a substance stays in a particular reservoir

evaportranspiration

sum of evaporation from bodies of water and ground surface and transpiration from plants and animals
