Earth Science Landscapes

  1. What are five factors that landscape topographic regions depend on?
    • 1. Bedrock Composition and Structure
    • 2. Climate
    • 3. Stream Drainage Patterns
    • 4. Elevation above sea-level
    • 5. Time
  2. When the ____________, the ____________ and the ______________ meet, landscapes are formed.
    Atmosphere, lithosphere, and hydrosphere
  3. What characteristic defines mountains?
    distorted rock structure
  4. In NY State, mountains generally consist of ____________ and ______________ rocks.
    Igneous, Metamorphic
  5. __________ are higher than lowlands but are lower than highlands.
  6. What is the main difference between a mountain and a plateau?
    A plateau has NO distorted rock structure, while a mountain does (plateaus are flat on top and have gentler slopes)
  7. When land is uplifted, what happens to gravity's force?
    It increases.
  8. When land is uplifted, the force of rivers __________.
  9. What type of geological feature are the Catskill Mountains considered?
    a dissected plateau
  10. How are sediments sorted on a plain.
  11. What are the two major plains in New York State?
    The Erie Ontario Plain, and the Atlantic Coastal Plain.
  12. __________ don't necessarily contain mountains, but they do signify where mountains used to be.
  13. What force must be dominant for Mountains and Plateaus to form?
  14. What are leveling forces?
    They are the erosion of high elevation features.
  15. What do leveling forces form?
    a plain
  16. What happens when the force of uplift is equal to the leveling forces?
    The elevations stay the same.
  17. Bedrock composed of stronger/tougher minerals will erode _______.
  18. What is the relationship between sediment strength, and the pitch of a slope?
    The stronger the bedrock, the steeper the slope.
  19. What is a landscape boundry?
    An area with a sharp change in elevation between two different adjoining bedrock structures.
  20. What is a ridge?
    A long narrow hilltop, mountain range, or watershed
  21. Why are ridges are very difficult to traverse?
    Because they have no mountain passes.
  22. What is the name for a long, steep slope that is often at the edge of a plateau or that separates areas of land at different heights?
    An escarpment
  23. What kind of climate is most likely to support steeper slopes with sharper edges?
    An arid climate
  24. What shape of mountain would be most likely found in a humid climate?
    A smooth rounded shaped mountain (eg, Mount Greylock, MA)
  25. Why do rocks in the desert tend to generally have steep slopes?
    Because there is more physical erosion in an arid climate.
  26. In deserts, why do mesas like this (in picture) tend to have a milder slope at the bottom, and a much steeper slope near the top?

    Because the rock near the bottom is weaker than near the top and has collapsed because of that.
  27. What type of mountains result from more chemical weathering than physical weathering?
    Smooth, and rounded mountains with gentle slopes.
