6. Which one of these is not a true aspect of the Bradshaw model?
- Velocity and discharge increase as you go downstream
- Gradient decreases as you go downstream
- Channel width decreases as you go downstream
- Particle size decreases as you go downstream
7. Which factor from the Bradshaw model explains why the HR should increase as you go downstream?
- Channel width (and depth) increases as you go downstream
- Velocity increases as you go downstream
- Gradient decreases as you go downstream
- Volume of load carried increases as you go downstream
8. Which one of the following describes stratified sampling?
- All data has the same possibility of being chosen
- Data divided into characteristics of choice i.e. Every blue flower
- Data with consistent increments i.e. every 10 metres
9. Which one of these characteristics of the 3rd order river is correct?
- 5km from residential areas
- truncated spurs
- In proximity to an old mine; mine debris along the river
- Close proximity to keswick
10. What secondary data was sought out during the fieldwork?
- Geographical textbooks; to identify theory behind the results of the fieldwork
- Webpages; to identify whether any chemicals were present in the river
- Previous fieldwork data; to plot scattergraphs to show impact of river over time
- Google maps; to show visual images of sections of the river that we didn't look at
11. What equipment was used in the method?
- Chain tape measure

- Pie chart
13. What is the spearmans rank coefficient?
- The constant of river erosion
- Subjective representation showing the extent of which two factors correlate
- Numerical representation showing the extent of which two factors correlate

- Hazard, Hazard management and impact on fieldwork
- None of the above
16. What method should be described?
- Collecting wetted perimeter
- Identifying rock characteristics
- Identifying width changes
- Identifying water temperature
17. What improvements can be done to the fieldwork for future students?
- All of the following
- Identify more stream orders to undergo the testing
- Use a metal tape measure instead of a plastic tape measure
- Collect a greater volume of data from the stream orders
18. What does critical value mean?
- A value used for Health & Safety regulations to determine the safety of the method
- Set of values that show the reliability of the data
- Set of values that decide how linked the two factors are
- None of the above
19. Which one of these characteristics of the 1st order river is incorrect?
- Permeable slate
- Impermeable slate
- Rough grazing; due to sheep raising
- Thin Soils; allowing quick infiltration
20. Which one of these characteristics of the 2nd order river is incorrect?
- Collapsing dry stone; impacting ability to measure whole river
- Deforestation; for human development
- Aforestation; for environmentally enhancing land
