Explain how the following factors influence wave deposition.
i) Gradient of the shore;
ii) Depth of the sea.

i) Gradient of the shore;
- A shore with gentle gradient reduces the velocity or speed of the flow of the backwash causing the waves to deposit the load on the shore. Where the shore is steep, the velocity or
speed of flow of the backwash will cause the materials to be moved from the shore back into the sea. There will be little or no deposition.

ii) Depth of the sea.
- Shallow water causes waves to break thus encouraging deposition. Where the sea is deep, there is less deposition because the sea bed is not in contact with the waves carrying deposits
