Coastal fieldwork - Geography GCSE

What are the steps of a geographical enquiry?

Introduction and planning, methods and data collection, data presentation and analysis, conclusions and evaluation.

What is reliability in a fieldwork context?

How consistent, accurate, and dependable your data and methods are, and whether repeating the investigation would give similar results.

What does tenuous mean in a fieldwork context?

Weak, uncertain, or not well supported — when talking about conclusions, data, or links between variables.

How can secondary data, such as a local geology map, help you plan a coastal fieldwork enquiry?

Helps identify rock types, choose suitable sites, predict erosion, and ensure safety when planning a coastal enquiry.

What equipment did we use at Porlock Bay to gather quantitative data?

Ranging poles, clinometer, calibers, tape measure.

What equipment did we use at Porlock Bay to gather qualitative data?

Power's scale of roundness.

What data did we gather at Porlock Bay?

Sediment size and shape, beach profile, annotated beach profile.

What are the advantages of random sampling strategy?

Reduces bias, each sample point has an equal chance of being selected, can be more statistically reliable.

What are the disadvantages of random sampling strategy?

May miss key areas or features, can be difficult to organise in the field, might give uneven coverage of the area.

What are the advantages of systematic sampling strategy?

Easy to carry out in the field, ensures even coverage across the area, simple to plan and organise.

What are the disadvantages of systematic sampling strategy?

May introduce bias if there is a pattern in the environment, can miss unusual or unexpected features, takes a lot of time.

What is GIS?

A computer-based system for storing, analyzing, and visualizing geographic data.

What is an enquiry process?

A method or strategy used to gather information and seek answers to questions or problems.

What are 2 examples of GIS tools?

Survey 123 and ArcGIS.

How can methods of data collection influence the reliability of conclusions?

Consistent, accurate, and appropriate techniques produce dependable data, while poor methods can lead to errors, bias, and unreliable conclusions.

What was the median rock size at Porlock Weir (the west) (length along the a-axis)?

13.5 cm.

What was the median rock size at Hurlstone Point (the east) (length along the a-axis)?

4.7 cm.

How many very rounded rocks were found at Hurlstone Point (the east)?

21.

What are the advantages of box plots?

Show the range, median, and spread of data clearly, help identify outliers easily, allow quick comparison between different sets of data.

What are the disadvantages of box plots?

Don't show individual data points, don't provide detailed information about data distribution, can be confusing if you're not familiar with how to read them.

What are the advantages of geolocated proportional circles?

Clearly show quantity differences at specific locations, easy to compare values across a map visually.

What are the disadvantages of geolocated proportional circles?

Difficult to accurately compare sizes of circles by eye, can be misleading if scale is not chosen carefully.

What are the advantages of radar graphs?

Show multiple variables on one chart, easy to compare patterns between different locations or times, visualize strengths and weaknesses clearly.

What are the disadvantages of radar graphs?

Can be hard to read with too many variables or datasets, difficult to interpret exact values, not suitable for very large datasets.

What were our three hypotheses at Porlock Bay?

Sediment will be larger on the west of the bay, sediment will be rounder on the east of the bay, the beach profile will be wider and taller on the east of the bay.

What was the total angle at Porlock Weir (West)?

67.

What was the total angle at Hurlstone Point (east)?

112.
