Q

glaciation

A

as land is uplifted, rivers erode into it creating v shaped valleys
ice ages bring glaciers to upland areas
a variety of features is left behind once it melts

Q

upland - weathering

A

freeze thaw creates scree slopes
scree is unstable and moves easily in rockfalls
heavy rain increases the risk of landslides

Q

lowland landscape - weathering

A

chalk is affected by chemical weathering
tree and shrub roots break up solid rock (biological weathering)

17
Q

lowland - post glacial river and slope processes

A

rivers form on clay soils, but not on chalk
slope processes are slow (soil creep)

18
Q

how does human activity change the landscape

A

planting
cleared land for farming

19
Q

tees exes line

A

from newcastle to plymouth

20
Q

north of the tees exes line

A

older, more resistant rocks
igneous and metamorphic
upland areas

21
Q

south of the tees exes line

A

younger, weaker sedimentary rock
easily lifted and folded
sandstone clay and chalk

22
Q

plucking

A

rocks are pulled from the back wall as water freezes to them

23
Q

scarp and vale

A

resistant rock, like chalk form steep escarpments

24
Q

human activities - agriculture

A

cleared land
field boundaries

25
Q

human activities - forestry

A

plant trees in a straight pattern, not native to the uk

26
Q

human activities - settlement

A

straightern river to build houses, land concreted over

27
Q

concordant

A

parallel

28
Q

discordant

A

perpendicular

29
Q

constructive

A

deposition, low frequency

30
Q

destructive

A

erodes, high frequency

31
Q

mass movement - sliding

A

when large sections of rock rapidly shift downslope along a straight slip plane

32
Q

mass movement - rockfall

A

when fragments of rock break away from the cliff face and fall

33
Q

mass movement - slumping

A

when material shifts downwards, rotating along a curved slip plane, usually as a result of becoming saturated

34
Q

solution

A

dissolved materials are carried along. you cannot see it

35
Q

suspension

A

small pieces of sediment are held in the water it looks muddy

36
Q

saltation

A

rocks bounce

37
Q

traction

A

rocks roll
