Landscape Development
THE SHAPE OF A LANDSCAPE IS ALSO KNOWN AS IT’S
Topography Depends on Several Factors : Climate Local bedrock Moisture,temperature,& latitude Composition of rocks
Human activities Mining, roads, cities, dams, agriculture
The general shape of a region Types of Landscapes in New York –Mountains –Plateaus –Plains
1.HIGH PEAKS AND DEEP VALLEYS (High relief) 2.STEEP SLOPES 3.STEEP STREAM GRADIENTS
4. Mostly METAMORPHIC ROCK 5. FOLDED/FAULTED/ TILTED ROCK
1.FLAT OR ROLLING HILLS 2.DEEP CUT STREAM VALLEYS (High relief) 3.HORIZONTAL LAYERS OF SEDIMENTARY ROCK
1.MOSTLY FLAT 2.HORIZONTAL SEDIMENTARY LAYERS 3.MEANDERING STREAMS
Notice how the different rock types weather differently Differences in rock resistance creates varied landscapes.
Humid Climate Arid Climate
THE INFLUENCE OF CLIMATE ON LANDSCAPE: HUMIDARID SLOPE SOIL WEATHERING SLOPE SOIL WEATHERING GENTLE S TEEP FERTILE ROCKY CHEMICAL DUE TO INCREASED AMOUNTS OF MOISTURE P HYSICAL DUE TO ABRASION
A Landscape results from the opposing forces of: UPLIFT EROSION (LEVELING)
IF UPLIFTING AND LEVELING FORCES ARE IN BALANCE, THE LANDSCAPE IS IN:
RIVER FLOW UNDERLYING LANDSCAPE
VOCAB! DISTRIBUTARY: Smaller rivers and streams fed by a larger one. TRIBUTARY: Smaller rivers and streams that feed into a larger one.
What is a watershed? The land area that drains water to a particular stream, river, or lake This area is usually surrounded by higher elevations
