Geopshere- Landscape Response To Environmental Change

Question 1

What 2 factors have a large impact on erosion rates and the type of erosion

Answer 1

Water/rainfall

Temperature

Question 2

Sea level change affects what parts of the river

Answer 2

Energy
Rivers feeding them
Form of the river

Question 3

Benthic is a proxy for …

Answer 3

Ice volume

Question 4

80 years from now what is the potential SLR

Answer 4

1 metre

Question 5

Give an example of a climate system feedback

Answer 5

Sea level changes

Thermohaline circulation

Question 6

Name 2 features of the last glacial maximum

Answer 6

Much less vegetation

Less desert and arid environments

Question 7

What does Schumms interpretation of Davis’s model show

Answer 7

Multiple stages in evolution. You will have intervals of heavy erosion then steady state to create ‘steps’ in the landscape

Question 8

What type of profile is there during glacial periods

Answer 8

Steep — less water flow so sediment can’t be easily transported, leads to deposition as opposed to erosion

Question 9

What is a fluvial knickpoint

Answer 9

Are the steepest points in a profile (usually waterfalls)

Question 10

What is equifinality

Answer 10

When different processes or environmental conditions can produce the same landform

Question 11

Name the causes of fan entrenchment

Answer 11

Para glacial decline in sediment supply
Difference between slope and river sediment transport regimes
Auto genie behaviour

Question 12

Landscape rejuvenation (incision) can be driven by

Answer 12

Tectonic uplift
