Swanage, Dorset
- Swanage is a seaside town in Dorset on the
south coast of England.
- There are bands of soft and hard rock. The soft rock
is made up of clay and sand and the hard rock is
made up of chalk and limestone.
- The bands of soft rock erode quicker than
the hard rock because it is made up of a
much weaker material. This leaves behind a
piece of land jutting out which is called a
headland.
- The areas next to the headland are called a bay.
The bay is made up of soft rock. In a bay you
normally find a beach with sand or pebbles.
- There is a bay along the shoreline of Swanage called Swanage Bay.
- There are lots of sand dunes in Swanage Bay. Sand
dunes are formed when the wind blows sand and
now it has caused mounds to appear along the
beaches.
- Maram grass is found on the sand dunes
- the roots hold the sand together as it is like its structure.
- At the end of the headland there is a stack called Old Harry and a stump called Old Harrys wife
- 1. Waves crash against a headlands with cracks in by hydraulic action. 2. repeated
erosion causes the crack to form a cave. 3. Continued erosion deepens the cave
and causes an arch. 4. The rock supporting the arch weakens and collapses. This
forms a stack. 5. When the stack is being eroded and it shrinks it is turned into a
stump.
