Geography Ice On The Land

Front 1

formation of a corrie

Back 1

- snow accumulates in hollow
- compressed into néve
- rotational slip
- plucking- back wall
- abrasion
- reduced erosion at front- lip
- tarn

Front 2

formation of an arete

Back 2

- erosion in 2 back to back corries
- land between become narrower
- knife edged ridge

Front 3

formation of a ribbon lake

Back 3

- glacier flow of hard/soft rock in trough
- erodes basin easily
- basin fills with water when glacier retreat
- water dammed by bars

Front 4

formation of a hanging valley

Back 4

- tributary glaciers
- glacier trough eroded more deeply
- ice melts, u shaped valley have waterfalls at cliff edge

Front 5

formation of truncated spurs

Back 5

- glacier can't flow around interlocking spurs
- bulldozes through
- steep cliff like edges on valley sides

Front 6

freeze thaw weathering

Back 6

- water gets into cracks in rocks
- low temps- freezes, expands, pressure on rocks
- temp rises- thaws, releases pressure
- weakens rock
- repeats and break rocks apart
- deposited as scree

Front 7

formation of a drumlin

Back 7

- formed under advancing glacier
- flat area- slower
- deposits ground moraine from plucking
- obstacle, traps sediment, builds up behind
- revealed when retreats
- tapered end points in direction of flow

Front 8

impacts of climate change on glacial area

Back 8

- winter sports
- tourists
- businesses
- jobs
- young move
- HEP
- avalanches
- sea level
- fish artificial snow- damaging
- pollutants
- have buy

Front 9

positive impacts of tourism in Chamonix

Back 9

- employment
- companies- campagne mont blanc
- locals benefit from infrastruture
- attractive
- local economy
- young stay

Front 10

negative impacts of tourism in Chamonix

Back 10

- traffic- pollution
- energy for facilities- global warming
- soil erosion
- avalanches
- noise
- litter
- tourist orientated
- houses
- conflicts
- plants trampled- less attractive

Front 11

management in Chamonix

Back 11

- avalanche barriers
- avalanche awareness courses
- traffic management
- Espace Mont Blanc
- Tommorow's Valley- burying electronic lines, maintaining footpaths, monuments/building
-artificial snow
- planning permission
- walkers in summer

Front 12

why do avalanches occur

Back 12

- 30*
- deforestation
- acid rain
- heavy snowfall
- temp rise
- rainfall
- off piste skiers
- vibrations
- wind direction

Front 13

management of avalanches

Back 13

- predictions
- explosions
- communication
- fences/barriers
- reforestation
