Step 1
Sea/marine action
Answer
The selected process is sea/marine action.
Formation of Coastal Landforms:
- Cliffs and Wave-Cut Platforms:
- Erosion: The action of waves eroding the base of the cliff leads to the formation of notch. Over time, this notch deepens and the upper part of the cliff undermines, causing it to collapse.
- Diagrams:
- Include a labeled diagram showing the cliff, wave-cut notch, and platforms.
- Beaches:
- Sediment Deposition: Material eroded from cliffs is transported by longshore drift and deposited in sheltered areas, forming beaches.
- Diagrams:
- Include a diagram illustrating the movement of sediment and beach formation.
Step 2
Formation of Landform 1
Answer
The first landform is Cliffs. Cliffs are formed through the constant erosive force of waves that impact against the rock face, gradually wearing it away.
Diagram:
- A diagram illustrating cliffs will show the rocky face, the wave energy, and where erosion has occurred. This illustrates how the upper cliff is affected over time.
Step 3
Formation of Landform 2
Answer
The second landform is Beaches. Beaches are formed from the sediment that is transported along the shoreline. This sediment can be made up of sand, pebbles, and other materials, deposited through the processes of wave action and longshore drift.
Diagram:
- A diagram must depict the movement of sediments along the beach and how they accumulate to form the beach.
