- How do sand dunes form?
- 1⇔Wind picks up loose sand and deposits it when the wind speed decreases.
- 2⇔Sand accumulates in areas where obstacles (e.g. rocks, plants) slow the wind.
- 3⇔A small mound of sand begins to form, and the dune starts to grow.
- 4⇔The wind continues to transport sand, building the dune higher.
- 5⇔Vegetation starts to grow on the dune, stabilising it.

Common misconception
Coastal landforms at the Jurassic Coast, such as Lulworth Cove and Old Harry Rocks, were formed quickly in a short period of time.
Coastal landforms at the Jurassic Coast, like Lulworth Cove and Old Harry Rocks, were formed over millions of years. Erosion, weathering, and the movement of tectonic plates have shaped these features gradually.
