  1. Landscapes and NY State

  2. 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)

  3. What forms landscapes? • Uplifting forces/Constructive-mountain building, continental accretion (converging plates, island arcs) • Leveling forces/Destructive-weathering,erosion,depostion cycle

  4. If forces are in balance then… • Landscape is in equilibrium (shows no change) • This rarely happens because one force is usually dominant over the other • What force is dominant in Westchester?

  5. Climate and Landscape • If dry -ARID-overall effect is jagged, angular and dry looking • If wet- HUMID-rolling, lowslope, grassy

  6. Old vs. New Landscape • OId-gentle rolling hills, wornaway, oxbow lakes etc… • New-Jagged mountains, more angular, steep slopes

  7. 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…

  8. Drainage Patterns Flat Land

  9. On plateaus

  10. Plateau or plains

  11. Mountains Volcanos

  12. Dome mountain With upturned layers

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