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 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 discuss the impacts of earthquakes in a developed and a developing 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 earthquakes.
Vocabulary To Learn
- magnitude: a measure of the energy released by an earthquake
- epicentre: the point on Earth's surface that is directly above where an earthquake happens underground
Common Mistakes To Avoid
- Tsunamis and landslides are primary impacts of earthquakes because they can cause massive damage to people and property.
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. 'magnitude'
a measure of the energy released by an earthquake.
3. Correct this common geography misunderstanding.
Mistake: Tsunamis and landslides are primary impacts of earthquakes because they can cause massive damage to people and property. Correction: Tsunamis and landslides are secondary impacts of earthquakes because they happen as an indirect result of an earthquake. For e.g, ground shaking destabilises slopes, making a landslide more likely, especially if there is then also heavy rain.
