Test 3 material

End


Eolian

EOLIAN

  • EQUALS WIND EROSION + WIND TRANSPORT + WIND DEPOSITION


Erosional capacity of wind

EROSIONAL CAPACITY OF WIND

  • ABILITY FOR WIND TO MOVE MATERIALS IS SMALL COMPARED TO ICE (GLACIERS) & WATER (RIVERS)


Deflation

DEFLATION

  • THE REMOVAL AND LIFTING OF INDIVIDUAL LOOSE PARTICLES

  • DESERT PAVEMENT


Blowout depressions

BLOWOUT DEPRESSIONS

  • RANGE IN SIZE FROM A FEW FEET DEEP AND A FEW FEET ACROSS TO 150 FEET DEEP AND SEVERAL MILES ACROSS


Abrasion

ABRASION

  • PARTICLES PICKED UP BY WIND CAN RUB ACROSS SOLID ROCK THEREBY FILING IT AWAY SIMILAR TO SANDPAPER


Wind transportation

WIND TRANSPORTATION

  • SALTATION - SKIPPING AND BOUNCING

  • SURFACE CREEP


Wind

ERG

  • SAND SEA THAT MOVES AS A UNIT


Sand dune movement

SAND DUNE MOVEMENT

  • STOSS - WIND

Loess

LOESS

  • DEPOSITS OF WIND BLOWN SOIL

  • MAY COME FROM DESERT REGIONS SUCH AS THE GOBI DESERT IN CHINA WHERE DEPOSITS OF 100-400 FEET OCCUR. YELLOW RIVER

  • GLACIAL /PERIGLACIAL REGIONS ALONG ILLINOIS & MISSISSIPPI RIVERS WITH 300 INCHES DEEP


Why is there a desert here

WHY IS THERE A DESERT HERE?

  • EASTERN FLANK OF THE SUBTROPICAL HIGHS


Arid landforms

ARID LANDFORMS

  • PLAYA IS SALT CRUSTS LEFT BY RUNOFF WATERS THAT EVAPORATE

  • ALLUVIAL FAN - MOUTH OF CANYON WHERE WATER EXITS INTO A VALLEY

  • BAJADA - INDIVIDUAL ALLUVIAL FANS COALESCE INTO ONE SLOPING SURFACE
