distinctive landscapes
landscapes
- visible features, make up surface of land
- natural (physical) and man made factors
- uplands, eg Grampians or Pennines, N and W, mountainous
- lowlands, flat/rolling, eg Cotswolds and S Downs, S
- geology
- permeability and hardness
- eg Chalk or Granite
- permeability and hardness
- glaciation
- scoured landscapes/ wear away
- eg. Lake district, N and wales
- Arétes, pyramid peaks, corries
- scoured landscapes/ wear away
climate and weathering
- uplands, more weathering. high precipitation, freezing temps = rivers, erosion. landslips/rockfalls.
- mech = freze-thaw, chem = acid, bio = root
- erosion
- geomorphic, hydraulic, attrition, solution, abrasion
- transportation
- suspension, traction, saltation, solution deposition.
Holderness Coastline
- Discordant (perpendicular) = headlands and bays/ Flamborough, Selwick's (differential erosion)
- chalk and till/boulder clay
- caves, arches, stacks, stumps
- hydraulic, abrasion weathering
- spit, Spurn head
- Yorkshire coast, 4.8km (3miles) long from Humber Estuary
- longshore drift (shingle/sediment)
- climate
- warmer summer =bio weathering, stormy winters = erosion, winter =freeze thaw
- human activity
- Hornsea = Groynes stop longshore
- Eastington = Rock Armour, absorb wave enrrgy
- Mappleton = 2x rock groynes,
- Withernsea = groynes + sea wall, reflect waye energy,
- Discordant (perpendicular) = headlands and bays/ Flamborough, Selwick's (differential erosion)
River Tees
- influence of climate
- upper = pre > evapo +2000mm impermeable bed, runoff + erosion
- upper = Freeze-thaw
- influence of Goemorphic
- waterfall = High Force. igneous dolerite carboniferous limestone (hydraulic, abrasion) 700m gorge
- Meander = Yarm (mid) differential erosion, river cliff, slip off slope
- Ox Bow lake = Hydraulic + abrasion, narrow neck, flood, break, cut off
- Floodplain = low, floods, friction, deposition, alluvium builds up
- Levées = croft-on-tees low, floods, deposition
- influence of human activity
- Cow green Reservoir 1967-1971, supply industry on Teesside, regulation, released
- Yarm flood defence, in Meander bend, £2.1m Defence system, hydro and abrasion
- dredging, improves navigation, deep water channel, increase discharge, more erosion/ transportation
- cutting meanders, faster, more erosion/transportation
- influence of climate
