Liz Bonnin introduces a clip examining the geology of the Jurassic Coast in southern England.
Liz Bonnin introduces the Jurassic Coast before Alice Roberts explains it's significance - it spans nearly 200 million years of Earth’s history and three geological time periods.
Alice explains the different rocks that can be found along this coastline (Cretaceous, Jurassic and Triassic) and why they formed.
Cake is used to demonstrate how the rocks have been deposited over time and how we are able to see them all in the landscape today.
This short film is from the the 鶹Լ series, Physical Geography with Liz Bonnin.
Teacher Notes
This short film could be shown in class before students have a go at applying their own knowledge through the use of cake to explain geological formations.
Students could watch and reinforce their knowledge of the geology and then come up with their own version of the analogy that Alice Roberts uses.
Curriculum Notes
This topic appears in geography at KS3 and KS4 / GCSE in England, Wales and Northern Ireland and National 4/5 in Scotland.
