Question 1
Which sampling technique involves selecting sites at regular intervals along a river profile?
- A) Random sampling
- B) Systematic sampling
- C) Stratified sampling
- D) Opportunistic sampling
Show answer
Answer: Systematic sampling
Systematic sampling is used to ensure an even spread of data points across a study area. By choosing sites at fixed intervals, such as every 100 metres, researchers reduce bias and ensure the entire length of the river is represented.

Question 2
What is the name of the piece of equipment used to measure the velocity of a river?
Show answer
Answer: Flow meter
A flow meter, often known as an impeller or hydro-prop, is submerged in the water to record the speed of the current in metres per second. It is essential for calculating discharge when combined with the cross-sectional area of the river.

Question 3
When measuring pebble roundness, which scale is typically used to categorise the shape?
- A) Richter scale
- B) Powers index of roundness
- C) Beaufort scale
- D) Mohs scale
Show answer
Answer: Powers index of roundness
The Powers index assigns a category from very angular to very rounded based on visual comparison with a standard chart. This allows geographers to quantify the effects of attrition as sediment is transported downstream.
