Coastal Landforms and Features Related to the Rock Type of the Area

Coastal landforms and features are related to the rock type (geology)

of the area.

To collect information for hypothesis1 we visited a number of places.

These are all recorded by number on the geological map of the Isle of

Purbeck. This also served as a location map (see M1 for details).

* Man O War Cove

* Lulworth Cove

* North Swanage Bay

* South Swanage Bay

* Redend point

* North Studland Beach

* South Studland Beach

* Sandbanks

* Bournemouth

* Durdle Door

* Stair Hole

* Old Harry's Rocks

We used a sheet to record the information collected in each area.

These included a grid reference, the landforms present, the rock type

of that area, the rock hardness, the cliff height and cliff profile,

if there was a cliff.

To determine the grid reference we used a map of the area and noted

the reference down in the classroom after we had returned from the

beach. The rock type of each place visited and the name of the

location were determined by the geological and location map of the

Isle of Purbeck (see M1). These maps being both secondary data were

given to us by the teachers as it would have been impossible to draw

our own maps and simpler this way than having to research maps for

ourselves. We also took rock samples at the beaches to study once we

got back to the classroom. The cliff profile was done on the beach

itself as a quick and simple pencilled sketch. We noted the landforms

present down in a notepad we had with us at the time. We then took

photographs of the landforms which we later annotated and drew

annotated field sketches in our notepads as well.

The rock hardness was determined on a scale of 1 to 10 with 1 as very

hard and 10 as very soft. The hardness was decided by:
