This set goes deeper on coasts from physical geography. Each question supplies a diagram or a small dataset, and your answer must use it.
The four lessons build in order, and the practice set mixes them.
What does this set cover?
- Tracing sediment movement along an original coastal diagram follows material along a beach using swash and backwash.
- Distinguishing erosional and depositional landforms sorts landforms by the process that made them.
- Explaining how a structure may change sediment distribution says which side of a groyne gains and which loses.
- Comparing coastal responses against a stated objective and limitation weighs options against a cost and an aim.
One short example: a groyne on an original beach
An original beach runs west to east, and sediment moves from west to east. A groyne is built across the beach. Sediment arriving from the west piles up against the western side and is blocked from reaching the eastern side.
If the western beach widens by 12 m and the eastern beach narrows by 9 m, the structure has not removed the problem. It has moved it along the coast.
| Side of groyne | Sediment supply | Change in beach width |
|---|---|---|
| West (updrift) | Blocked, so it builds up | Wider, +12 m |
| East (downdrift) | Cut off, so it is starved | Narrower, −9 m |
How do the parts connect?
Sediment movement is the base skill. Landforms record where material is taken away or dropped, structures interrupt the movement, and management choices weigh what the interruption costs.
Who should start where?
- Name landforms but cannot say how they formed: start with sediment movement.
- Mix up which landforms are built up and which are worn away: start with erosional and depositional landforms.
- Swap the two sides of a structure: start with the structure lesson.
- Asked to pick a scheme: start with the comparison lesson.
