Landscapes and NY State
Major Points:Landscape characteristics are the result of
the interaction of forces of crustal movement, people, and climate
Underlying bedrock determines the landscapes- why?
Three types: Mountains(Highlands), Plateaus(Uplands), and Plains(Lowlands)
What forms landscapes?Uplifting forces/Constructive-mountain
building, continental accretion (converging plates, island arcs)
Leveling forces/Destructive-weathering,erosion,depostion cycle
If forces are in balance then…Landscape is in equilibrium (shows no
change)This rarely happens because one force is
usually dominant over the otherWhat force is dominant in Westchester?
Climate and LandscapeIf dry -ARID-overall effect is jagged, angular
and dry lookingIf wet- HUMID-rolling, lowslope, grassy
Old vs. New LandscapeOId-gentle rolling hills, wornaway, oxbow
lakes etc…New-Jagged mountains, more angular, steep
slopes
Cliffs or escarpments:Cliffs result from rock that varies in rock
resistance (resistant rock juts out in a series of rock layers due to its composition- it resists weathering…

NY Watersheds:Watershed-geographic area that drains into a
stream (land around a stream)
