  1. Surface Processes:What are they doing to Earth?

  2. Say “hi” to Steve!

  3. LANDSCAPES

  4. Have out p. 2 of your ESRT

  5. an area of high elevation made by uplifting forces. Rocks are usually metamorphic due to compression, faulting, folding, tilting or deformation. Mountain

  6. Himalaya Mountains, India

  7. Rocky Mountains, Colorado

  8. Folded mountain in Death Valley, CA

  9. Adirondack Mountains, NY

  10. Plateau an area of medium elevation made of horizontal sedimentary rock. Often flat but heavily dissected (cut) by streams so that they have steep valley slopes and appear to be mountains.

  11. Grand Canyon, Arizona

  12. Allegheny Plateau, NY

  13. Letchworth State Park Located in the Allegheny Plateau Landscape Region of NYS Notice the horizontal bedrock

  14. Cattaraugus Creek Also located in the Allegheny Plateau Landscape Region Again, notice the horizontal bedrock That’s Dr. Sarah

  15. Catskill “Mountains”, NY

  16. Valley an area of low elevation between two mountains, hills, or ridges. Usually formed by a river.

  17. Tibet Valley, China

  18. Vail Valley, Colorado

  19. Plain an area of low elevation made of horizontal sedimentary rock.

  20. Great Plains, Midwest US

  21. Savanna Plains, Africa

  22. Long Island, NY Located in the Atlantic Coastal Plain Landscape Region Made of horizontally-deposited glacial sediment

  23. Erie Canal, NY Located in the Erie-Ontario Lowlands Landscape Region

  24. That’s Dr. Masa Whirlpool Gorge, Niagara Falls, NY Located in the Erie-Ontario Lowlands Landscape Region Notice the horizontal bedrock, I guess some might classify this as a plateau, depending on your viewpoint.

  25. OR OR

  26. WHAT CAUSES DIFFERENT LANDSCAPES TO FORM? • Constructive or destructive forces • Harder or softer bedrock • Cool or warm, wet or dry climate

  27. FORCES Constructive Uplifting forces • Mountain building • Volcanoes • Sea-floor spreading

  28. FORCES Destructive Leveling forces • Erosion and Weathering (together!) • Land subsidence (sinking) • Gravity • Water (the main leveling force) • Wind • Ice

  29. Bedrock BEDROCK All the solid rock under this stuff

  30. BEDROCK • Harder bedrock are more resistant to weathering and erosion and form high cliffs and hills. • Softer bedrock is less resistant to erosion and form valleys. Resistance of rock means it doesn’t erode easily. Harder rock resists erosion more than softer rock.

  31. CLIMATE Temperature Moisture

  32. CLIMATE • Warm climates generally speed up weathering • Cold climates have ice erosion • Dry climates – angular features & steep slopes • Wet climates – smooth features & rolling hills

  33. Arid Landscape

  34. Moist Landscape
