Trans alaskan pipeline system (TAPS)

124,000 heated pipes // 800 miles // 17Bn barrels through // $8Bn // Denali fault 2002 magnitude 7.9 ruptured 336 km // Exxon Valdez oil spill 1989 11M gallons 250,000 sea birds // 75% over permafrost // 420 miles elevated // zig zags for movement

1 of 12

Red Tarn

corrie glacier // steep backwall // Randkluft // Bergschrund // meltwater abrasion // rock lip

2 of 12

Borrowdale

valley glacier // accumulation // input snowfall // snow line // ablation // higher output melting

3 of 12

the How

striations // roche mountonnee // stoss side // band of resistant rock (abrasion // meltwater // ice compression ) // lee side (plucking // extend flow of ice)

4 of 12

Watendlath, Cumbria

hanging valley either side of truncated spurs // arete // ribbon lakes // misfit stream // pyramidal horn

5 of 12

Crow park, Keswick

Drumlin // boulder clay // stoss end is sort // less slope long // melting causes competence loss + deposition

6 of 12

Rosthwaite / Watendlath

TRANSVERSE - push moraine // recessional moraine // end moraine // terminal moraine // LONGITUDE - lateral moraine // medial moraine

7 of 12

after Rosthwaite, Borrowdale (fluvioglacial erosion)

ice marginal channel // melts as cannot travel through TUFF rock // sorted deposits // V shaped valley

8 of 12

Rosthwaite, Borrowdale (fluvioglacial deposition)

beaded esker // varves // kames // kame terraces

9 of 12

surprise view, Borrowdale

weathering // freeze thaw // 9.05% // 22d.c // 2115kg/cm^2 // migrations over 0d.c // scree slope // hydration // 1000kg/cm^2 // swelling + minerals absorb different // chemical // carbonation (meltwater more soluble) // little biological (cold)

10 of 12

animal adaptations

change diet // fur/feather colour change // thick insulation // waterproof // short arms, legs + small ears // winter hibernation

11 of 12

plant adaptations

rhizomes (shallow roots allow spread still) // low lying (less evap.) // shallow roots (permafrost) // tubers (starch storage) // lots of chlorophyll // small leaves (water retention)
