Landscape  Development
LANDSCAPE REFERS TO THE GENERAL  SHAPE  OF A REGION
THE SHAPE OF A LANDSCAPE IS  ALSO KNOWN AS IT’S TOPOGRAPHY
We describe landscape regions in terms of the:  ,[object Object],[object Object],[object Object],[object Object]
Landscape regions can be classified as one of the following: ,[object Object],[object Object],[object Object]
MOUNTAIN
folds tilts faults MOUNTAIN
 
 
 
 
 
[object Object],[object Object],[object Object],[object Object],[object Object],MOUNTAIN
PLATEAU

[object Object],[object Object],[object Object],PLAIN
Topography Depends on Several Factors : ,[object Object],Moisture,temperature,latitude Composition of rocks Mountains,Valleys roads,cities, dams,agriculture Mining ,[object Object],[object Object],[object Object]
INTERFACES * ,[object Object],[object Object],[object Object]
Landscapes of New York State: ,[object Object],[object Object]

Most of New York State soils are not  residual, they are ,[object Object],[object Object]
LANDSCAPE DEVELOPMENT: ,[object Object],[object Object],[object Object]
UPLIFT IS OFTEN  CAUSED BY: PLATE  TECTONICS
THE RESULTING GEOLOGIC EVENTS INCLUDE: ,[object Object],[object Object],[object Object],[object Object]
MOUNTIANS
THE MOST IMPORTANT LEVELING AGENT TODAY IS ,[object Object],[object Object]
Notice how the rock types weather differently Which rock is least resistant? shale Differences in rock resistance creates varied  and interesting landscapes.
Folding is part of the  mountain building process
OTHER LEVELING AGENTS INCLUDE: ,[object Object],[object Object],[object Object],[object Object]
IF UPLIFTING FORCES HAVE BEEN DOMINANT THE LANDSCAPE WILL BE MOUNTAINOUS
IF LEVELING FORCES (EROSION) HAS BEEN DOMINANT THE LANDSCAPE WILL BE: PLAINS (FLAT) PLATEAU
IF UPLIFTING AND   LEVELING FORCES ARE IN BALANCE, THE LANDSCAPE IS IN: DYNAMIC EQUILIBRIUM
THE INFLUENCE OF CLIMATE ON LANDSCAPE: gentle Fertile Thick A layer Chemical due to Increased amount  Of moisture steep rocky Physical due to abrasion Type of Weathering Soil Slope Arrid (dry) Humid (moist)
SOIL HORIZONS (LAYERS) ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object]

A CHANGE IN CLIMATE CAN ALSO CREATE AN   ICE AGE
WHICH LEADS TO GLACIERS AND GLACIAL LANDSCAPES

GLACIERS DEPOSIT _______________  SEDIMENTS. UNSORTED
BEDROCK ACTED UPON BY GLACIERS IS GENERALLY POLISHED AND ,[object Object],[object Object],[object Object],[object Object]
Glacial valleys are generally  U- SHAPED
escarpment U-shaped valley
WHILE RIVER VALLEYS ARE: V- SHAPED
COASTAL LANDSCAPES: ,[object Object],[object Object],[object Object]
 
 
THE BEDROCK OF IN AN AREA WILL CAUSE STREAMS TO DRAIN IN A PATTERN
[object Object],[object Object],[object Object],DRAINAGE PATTERNS
Mississippi River Delta
 
Match the geologic structures below To the drainage patterns they would create.
THIS   OCCURS   WHEN:   Rock resistance is all similar
THIS   OCCURS   WHEN:   WATER FLOWS IN THE PATH OF LEAST RESISTANCE Rock resistances are different
WATER FLOWS DOWN HILL FOLLOWING THE PATH OF  LEAST RESISTANCE
FOLLOWING THE PATH OF  LEAST RESISTANCE
STAGES IN LANDSCAPE DEVELOPMENT: ,[object Object],[object Object]
THE 3 STAGES OF LANDSCAPE MATURITY :
[object Object],[object Object],[object Object],[object Object],YOUNG
[object Object],[object Object],[object Object],MATURE
[object Object],[object Object],[object Object],[object Object],OLD
CAN CAUSE OLD LANDSCAPES TO BE REJUVINATED  BACK TO YOUNG AGAIN UPLIFT
THE INFLUENCE OF HUMANS: ,[object Object],[object Object],TECHNOLOGY
WE CAN MAKE CHANGES IN THE LANDSCAPE IN A  FEW MONTHS THAT WOULD TAKE NATURE  HUNDREDS OF YEARS  TO ACHIEVE
It could also take  hundreds of years  to remedy the  effects of  technology . negative
