Study Hub
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 lead to tectonic hazards and investigates the geographical pattern of hazards across the world. Pupils will also learn how tectonic hazards affect people in different places and how people seek to manage hazards.
Lesson Summary
You will learn to describe the structure of Earth and how the pattern of earthquakes and volcanoes relate to Earth's tectonic plates.
Key Notes
- Earth is made up of four main layers: the inner core, outer core, mantle and crust.
- Together the upper mantle and the crust form Earth's rigid outer layer: the lithosphere.
- The lithosphere is broken into large sections or tectonic plates.
- Most earthquakes and volcanoes occur at plate boundaries.
Vocabulary To Learn
- pressure: a force pushing or pressing on a given area
- density: density is the mass of something compared to its volume
- tectonic plate: the huge pieces that Earth's crust is broken into
- plate boundary: the point where two tectonic plates meet
Common Mistakes To Avoid
- Earthquakes and volcanoes happen on tectonic plates.
3 Quick Questions (With Answers)
1. Explain this geography topic using two clear key points.
Earth is made up of four main layers: the inner core, outer core, mantle and crust. Together the upper mantle and the crust form Earth's rigid outer layer: the lithosphere.
2. Define this geography term and use it in an example. 'pressure'
a force pushing or pressing on a given area.
3. Correct this common geography misunderstanding.
Mistake: Earthquakes and volcanoes happen on tectonic plates. Correction: Tectonic plates cover the whole world, this would mean they happen everywhere. The majority of earthquakes and volcanoes occur at plate boundaries (where two plates meet), though there are some which happen away from boundaries.
