7. Hypothesis
• Not a question
• Statement
• Something that you believe in,
that can be tested by the data
we are collecting.
8. Beach Profile
• Measurements that are taken to measure
gradient
• Normally a few transacts are taken.
• Comparison of different transacts can be
done.
–Strength of waves –
destructive/constructive waves
–Effectiveness of coastal protection
measures
9. Longshore Drift
• Use of flotation device to
measure the speed of longshore
drift.
• Impact on the strength of the
waves
• Linked impact on gradient of the
beach
10. Sample (Coast)
GI questions (4-6m)
• Fig 2 shows students collecting data at a
beach. Explain what you think they are
doing and what can the data show. (5m)
• Using the data , plot the beach profile at
transact A and B.
• What precautions should you take when
conducting such fieldwork?
11. Sample (Coast)
Explanation questions (4-6m)
• Briefly explain how constructive waves
and destructive waves differ.
• With the aid of a suitable, fully-labelled
diagram, explain how sediments are
moved along the coast.
• Besides Attrition, explain how the other 3
coastal erosional processes help create
the coastal landforms shown below.
12. Sample (Coast)
Explanation questions (4-6m)
• Explain how headlands and bays are
formed.
• Explain how human activity affects the
rate of coastal erosion.
• Briefly explain why the waves around
Australia are suitable for windsurfing.
13. Sample (Responses)
Comparison (open-ended) 8m
• Factor X is the most important factor
that that erodes a coast made of
limestone. How far do you agree… …
• Assess how effective prop roots are
in helping mangroves survive in salt
water.
