EXAM LINK (OL)
Landform Development (40 marks)
Explain, with the aid of diagrams, the formation of any two landforms.
2018, Q2B Marking Scheme:
Formation of any two landforms = 2 × 20 marks For each landform: landform = 1 mark
diagram(s) = 2 aspects × 2 marks
Formation explained = 5 SRPs × 3 marks. At least one SRP must explain a relevant process.
EXAM LINK (HL)

2016, Q1B Marking Scheme:
Named landform = 2 marks
Examination = 14 SRPs × 2 marks

1. Describe what an oxbow lake looks like. 2. How does a mort lake form? 3. List and explain two reasons sediment is deposited in the river mouth. 4. Describe two differences between the bottomset bed and the topset bed. 5. Explain the difference between a tributary and a distributary. 6. Where are lacustrine deltas formed? Give an example of where one can be found.
Cuspate delta Example: Tiber Delta, Italy
Strong waves hit the river head-on, causing the deposited sediments to be spread in the shape of a tooth along a straight coastline (Fig. 8.24).

Bird’s foot delta Example: Mississippi Delta, USA
A bird’s foot delta is formed where the waves are weaker than the flow of the river. Sediment gathers along the edges of a small number of distributaries, giving the appearance of an out-stretched bird’s claw (Fig. 8.23).
