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 tectonic hazards, their location, causes and effects. Pupils learn about the different types of hazard before focusing on earthquakes and volcanoes. Pupils will learn about tectonic processes, hazard impacts and the options for mitigation and adaptation.
Lesson Summary
You will learn to use located examples to assess the impacts of volcanic eruptions in a developed and an emerging country.
Key Notes
- Primary impacts are immediate and caused directly by the tectonic hazard.
- Secondary impacts are indirect impacts and occur in the hours, days and weeks after the hazard.
- There is a range of reasons why primary and secondary impacts may differ between two volcanic eruptions.
- Different indicators can be considered to assess the significance of primary impacts and secondary impacts.
Vocabulary To Learn
- primary impact: the immediate impacts of a tectonic hazard which are directly caused by it
- secondary impact: indirect effects that occur as a consequence of a tectonic hazard's primary impacts
Common Mistakes To Avoid
- Impacts of volcanic eruptions are always more severe in developing and emerging countries than in developed countries.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
Primary impacts are immediate and caused directly by the tectonic hazard. Secondary impacts are indirect impacts and occur in the hours, days and weeks after the hazard.
2. Define this geography term and use it in an example. 'primary impact'
the immediate impacts of a tectonic hazard which are directly caused by it.
3. Correct this common geography misunderstanding.
Mistake: Impacts of volcanic eruptions are always more severe in developing and emerging countries than in developed countries. Correction: A lot depends on the eruption type and factors such as population density. Economic impacts are often highest in developed countries because of the higher value of the property impacted by the eruption.
