Level 4 DESCRIBE:What was the Holbeck Hall?Where did it happen?What happened?Who did it effect?When did it happen?
Level 5 EXPLAIN:What factors cause cliffs to collapse?Uses and explains freeze thaw and chemical weathering?Uses and explains the types of wave erosion- Hydraulic action? Abrasion? Solution? Attrition?How did rain effect the cliff?How did weathering effect the cliff?How did wave erosions effect the cliff?Why did the clay in the cliff make a collapse more likely?
Level 6 Include a conclusion to link all these ideas to show that it was likely that one day the cliff would collapse.
Holbeck Hall Hotel Newspaper ArticleMake sure your article include the following ideas. Succeed by making sure that all
these ideas are discussed using the Point Evidence Explain Explore Language (PEEEL) approach.
Use the Self and Peer assessment sheet that is also in this Learning Zone folder to help you check that you included every thing that you need to.
Use the following slides to remind you of key information.
Remember:
Describe- What? When? Where? Who? Level 4
Evidence- facts and quotations Level 4
Explain- Why? How? Level 5
Conclusions- that link ideas together Level 6
Images to make you think…

What happened?
Cliff Collapse
Weathering
Chemical: rain soaks in and dissolves minerals
Freeze- thaw: In winter water freezes in the cracks making them larger
Rain
Soaks into the cracks. It makes clay cliffs very slippery. The clay can just
slide away.
Wave Erosion
Waves attack the cliff through Hydraulic Action, Abrasion,
Solution and Attrition.
Explain how these
processes weaken cliffs
Explain what the key words and processes
mean!

A Useful Quote:
• “In dry summers, cracks can develop in the clay cliffs. Then if you get a wet winter, the water gets in through the cracks and lubricates the clay” Engineer from Scarborough Council
