EXTERNAL GEOLOGICAL PROCESSES
ICE
depositional landforms
medial moraine
located in the middle of the glacier
termonal moraine
located in the front of the glacier
lateral moraine
located in boths sides of the glacier
glaciar landforms
arête
lake
horn
handing valley
U-shaped valley
2 errosion processes
2- abrasion
1- pluking
parts of the ALPINE Glacier
cirque
rounded shape, snow accumulates transform sin to ice
glacial valley
also called the ice tongue
terminal zone
lowest section, ice melts
definition of
iceberg
frozen seawater
glacier
is a thick mass of ice that moves over land
types of glacier
1-
alpine glaciers
found in the mountain ranges at high elevations
2- continental glaciers
aren't confined by topografy
SEA
two water movements causing of erosison
tides, oscillations in the sea level
waves, causing by the action of the wind on the surface
landforms caused by erosion
headlands and bays
natural bridges
wave.cut platforms
cliffs
seastacks
2 methods for transport of eroded material
longshore drift, occurs when the direction of the wind and the waves
waves, drags material in towards the beach
landsforms caused by deposition
lagoons
spits
deltas
tombolos
marshes
beaches
sandbars
WIND
erosional landforms
mushroom rocks
honeycombs
desert pavement
definitions of...
1-deflaction
is the process were the the wind detaches and removes loose particles from the surface of the Earth
2-abrasion
the impacat and frinction of this matireal on rocks polishes and wears away at them
two conditions for erosion
presence of loose material, can't move solid rock or large fragments
absence of vegetation, plant roots help the soil in pace
depositional landforms
duene, mound of sand transported by wind
loess, extensive deposit of fine-grained particulate matter
