Study Guides
This pupil-friendly study guide includes a unit summary, clear notes, common mistakes, and quick questions with answers.
Unit Summary
This unit teaches pupils about the physical processes that create and alter different types of rocks and soils over time. Pupils will also develop their understanding of how humans use different rocks and soils and why this can affect geographical patterns of wealth and population.
Lesson Summary
You will learn to identify the key features of limestone, and describe different limestone landscapes.
Key Notes
- Limestone is a sedimentary rock made of calcium carbonate.
- Grykes are deep cracks on the surface on limestone formed by chemical weathering.
- Clints are exposed blocks of limestone separated by grykes.
- Limestone landscapes include limestone pavements, such as Malham Cove, and limestone caves, such as Gough's Cave.
Vocabulary To Learn
- limestone: a hard sedimentary rock
- grykes: deep cracks on the surface of limestone pavements
- clints: exposed blocks of limestone
- solution: a form of chemical weathering where rock is slowly dissolved by acidic water
- limestone pavement: flat, exposed area of limestone
Common Mistakes To Avoid
- Some students may think that grykes and clints are type of rock, rather than being a feature of limestone landscapes.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
Limestone is a sedimentary rock made of calcium carbonate. Grykes are deep cracks on the surface on limestone formed by chemical weathering.
2. Define this geography term and use it in an example. 'limestone'
a hard sedimentary rock.
3. Correct this common geography misunderstanding.
Mistake: Some students may think that grykes and clints are type of rock, rather than being a feature of limestone landscapes. Correction: Students will be taught what clints and grykes are in relation to limestone.
