distinctive landscapes

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