Geography GCSE: Castle Inn Quarry (Snowdonia National Park)

Geologist and keen climber Dr Tom Challands challenges a pair of young people each to climb a rock face and see just what can be revealed from this unique vantage point, on the rock face rather than observing from the ground.

The climbs are not only technically demanding but throw up different field study challenges for the team to solve.

This location is a sheer climb at Castle Inn Quarry North Wales.

These experienced climbers face the task of finding evidence from the rock to see how it was formed and also if human activity has played its part in what we see today.

This clip is from the series Rock Types at Great Heights.

Teacher Notes

Could be used to introduce elements of the geology, geography and earth science syllabus, or in preparation for field studies.

Before showing the clip, students could be asked how they would identify limestone landforms - both through the physical appearance of the landform (bedding plains) and through chemical tests (hydrochloric acid test).

Students can be encouraged to note down features of the limestone while watching the clip, and compare this to their prior ideas for tests.

Students could also be asked to compare features of a sedimentary rock like limestone to an igneous rock like granite.

Curriculum Notes

This clip will be relevant for teaching GCSE Geography and Social Studies. This topic appears in OCR, AQA, Edexcel, WJEC KS4/GCSE in England and Wales, CCEA GCSE in Northern Ireland and SQA National 4/5 in Scotland.
