Lake district- UK glacial landscape Flashcards
arete
a narrow ridge of rock that separates 2 valleys
corrie+ formation
horseshoe shaped valley that is formed via freeze-thaw weathering from a block of compressed snow. The ground moraine from the freeze-thaw weathering falls to the bottom of the snow and erodes the ground beneath. This creates an armchair chaped valley.
drumlin formation
a tear shaped rock formation that points in the direction of glacial movement
hanging valley formation
tributary glacial travels into main glacial/ u shaped valley
outwash
material carried from a glacier by freshwater
ribbon lake
a glacial trough where the ice melts and forms a long, shallow lake
till
glaical sediment
truncated spur
the ridge that forms either side of a u shaped valley
lowland and upland example
lowland- fens in east anglica
highland- cumbrain mountains inj LD
glacial period
where temps drop to 11 degrees average
striations
smooth grooves at the bottom of a glacier formed by abrasion from ground moraine
outwash
deposit of sand and gravel carried by running water from the melting ice of a glacier and laid down in stratified deposits.
