Exam code: 1GA0
A group of students collected data to investigate coastal processes at six sites along a beach.
Describe one fieldwork method that could have been used by the students to measure sediment size.
Explain one disadvantage of using this fieldwork method

The students measured sediment size along the beach and presented this data on a scatter graph.
Study Figure 2a below.
Complete Figure 2a by plotting the data below
Distance along the beach (m) | Mean sediment size (cm) |
|---|---|
400 | 6 |
1200 | 3 |

Study Figure 2b in the Resource Booklet.
Calculate the mean gradient of the beach.
Give your answer to one decimal place.
You must show your working in the space below
Mean gradient .............................................................. °
Identify the two correct statements about the beach data in Figure 2b.
the beach gradient increases between site 1 and site 6
the mean sediment size decreases overall between site 1 and site 6
the mean sediment size increases between site 3 and site 4
the beach gradient decreases between site 2 and site 3
the mean sediment size is twice as large at site 2 than it is at site 1

Figure 2a
Bar chart showing the mean sediment size at six survey sites from west to east, along the coastline
Figure 2b
Scatter graph showing the beach gradient at one survey site
Study Figures 2a and 2b in the Resource Booklet.
A group of students investigating a coastline expected:
sediment size to decrease along the beach from west to east
gradient (slope angle) of the beach to decrease from the cliff to the water’s edge
After analysing Figures 2a and 2b, the students concluded that changes in gradient were more in line with their expectations.
Assess the extent to which you agree with this conclusion.

Figure 2
1:50,000 OS map of a coastal landscape in East Yorkshire
Study Figure 2 in the Resource Booklet.
A group of students used this 1:50,000 OS map extract to suggest the following two possible enquiry questions to investigate this coastal landscape.
The direction of longshore drift is north to south from 20 48 to 21 46 1. Does coastal management affect beach morphology? 2. Does the sediment size increase from north to south? |
Evaluate which one of these enquiry questions would be the most suitable.
