What is the fieldwork hypothesis or enquiry question for the Dawlish Warren investigation?

• ‘The sea defences at Dawlish Warren are effective’

• ‘The sand dunes at Dawlish Warren are increasing in size’

• ‘The population of Dawlish Warren is declining rapidly’

• ‘The climate at Dawlish Warren is becoming colder each year’

What is Dawlish Warren formed by?

• Dawlish Warren is a sand spit formed by long shore drift and deposition.

• Dawlish Warren is a limestone plateau formed by volcanic activity.

• Dawlish Warren is a granite outcrop formed by glacial erosion.

• Dawlish Warren is a clay basin formed by river meandering.

Which of the following is an example of hard engineering used at Dawlish Warren?

• Dune regeneration

• Beach nourishment

• Groynes

• Planting trees

Which of the following is an example of soft engineering used at Dawlish Warren?

• Sea walls

• Rip rap

• Dune regeneration

• Concrete barriers

List the three criteria used to manage risk during the Dawlish Warren fieldwork and briefly explain each one.

• S – safe to carry out, A – accessible, P – possible. Safe: risk assessment and actions to limit risk; Accessible: easy to get there; Possible: can be done in the available time.

• S – secure, A – affordable, P – practical. Secure: ensure no theft; Affordable: within budget; Practical: easy to organize.

• S – simple, A – accurate, P – permanent. Simple: easy to understand; Accurate: correct data; Permanent: lasting results.

• S – sustainable, A – adaptable, P – predictable. Sustainable: environmentally friendly; Adaptable: can change plans; Predictable: outcomes are known.

What is the first stage in the Six Stages of Enquiry?

• Think of a suitable question or hypothesis to investigate.

• Collect and record data.

• Analyse the results and draw conclusions.

• Present your findings to others.

Describe what a spit is and how it forms, based on the diagram and explanation provided.

• A spit is an extended stretch of sand or shingle jutting out into the sea from the land, formed by longshore drift and deposition. It forms when there is a change in the shape of the coastline, and sediment is carried by longshore drift and deposited, creating a ridge.

• A spit is a type of underwater volcano that erupts and forms new islands.

• A spit is a deep trench in the ocean floor created by tectonic activity.

• A spit is a mountain formed by the accumulation of lava flows over time.

Why is Dawlish Warren at threat from erosion?

• It is at threat from erosion because it is a sand spit and a popular destination, making it vulnerable to natural processes and human activity.

• It is at threat from erosion because it is located in a mountainous region with frequent landslides.

• It is at threat from erosion because it is surrounded by dense forests that trap water.

• It is at threat from erosion because it is built on solid rock, making it unstable.

What combination of methods did you use for your fieldwork?

• Only Qualitative methods

• Only Quantitative methods

• Qualitative, Quantitative, Primary and Secondary methods

• Only Primary methods

What is stratified sampling used for in this fieldwork?

• To choose sites on the section of coastline.

• To measure the height of the waves.

• To record the temperature of the water.

• To identify the type of rocks present.
