Part 1: Describe some of the physical processes through which landscapes are shaped
and a river can form a canyon. - ANSWERSWeathering [1] breaks down rock in situ [1].
Through physical [1], chemical [1] or biological [1] processes. Physical weathering
would be more effective in the climate of Yellowstone [1].
Erosion [1] moves the weathered fragments [1]. The river can erode the weathered
fragments [1], and transports material through bedload [1], saltation [1], suspension [1]
and dissolved load [1].
Over lots of time [1] the river can erode the rocks [1] through the force of the water
acting on the material [1] carving out the canyon/valley [1], which typically has a v-
shape [1].
Part 2: Describe some of the methods through which you could mitigate the hazards
associated with mass movements - ANSWERSDevelopment of early warning systems
[1] and forecast systems [1].
Engineering to: reshape topography [1], strengthen slopes with rock bolts [1] or gabions
[1], draining water [1], controlling erosion [1], rock nets [1], concrete bridges [1].
Part 3: Which type of rock, sedimentary, metamorphic or igneous, would be most
common in the park? - ANSWERSIgneous
Part 4: Describe methods you might use to monitor volcanic activity in the park. -
ANSWERSUnderstand the volcano's history [1], past eruptive style [1].
Ground based monitoring [1]: seismic recording stations [1], ground deformation
sensors [1], infrasound [1], gas analysis [1], water analysis [1], thermal imagery [1],
groundwater level monitoring [1].
Satellite observations [1]: ground deformation [1], thermal anomalies [1], atmospheric
gases [1].
Part 5: What type of renewable energy would be most useful to power these facilities
and why? - ANSWERSGeothermal [1] high heat energy from volcanic activity [1]
