2. Managing Earthquakes and Volcanoes
Use this PowerPoint in conjunction with your books to help you revise

3. What do you need to revise?
Plate boundaries (constructive, destructive, conservative)
How earthquakes and volcanoes form at each plate boudary
Impacts of Mt St Helen’s volcanic eruption (on people and environment)
Kashmir and Los Angeles earthquakes: impacts explained (think about the difference between rich and poor countries)
Reasons why people live near earthquakes and volcanoes

4. Plate boundaries Kung Fu plate Boundaries video
Plates meet in three ways:
By moving apart (constructive)
By moving together (destructive/collision)
By moving past each other (conservative)

5. Plate boundary
Diagram
Explanation
Constructive
Two plates move apart and magma rises up to fill the gap. This forms new crust and create volcanoes. Earthquakes can also happen as friction builds up when the crust moves over the mantle.
Destructive
An oceanic and a continental plate move together and the heavier oceanic crust is forced/subducts under the continental plate. The oceanic crust melts and creates new magma which then rises up through the continental crust to form a volcano. Earthquakes also happen here as friction builds up when the two plates move past each other.
Collision
Two continental plates move together. Neither can sink so both are forced upwards to form mountains.
Conservative
Two plates are sliding past each other (in opposite or the same direction) but at different speeds. This causes friction to then build up which is eventually released as an earthquake. No volcanoes happen here.

6. Mt St Helens

7. Kashmir/Los Angeles Earthquake
How does being in a rich or poor country affect what the effects of an earthquake will be?

8. Why do people live near volcanoes and earthquakes?
Too poor to move
Fertile soils
Geothermal energy
Reasons
Don’t care
Sacred place
Mining
Family links/tradition
Tourism

9. Extreme Environments
You should use this PowerPoint in conjunction with your exercise book to help you revise.

10. You need to know… Types of extreme environment (hot, col, dry and wet)
Challenges/difficulties of living in extreme environments
How to read a climate graph
Plant and animal adaptations to hot/dry environments

11. Hot environments: adaptations
Plants
Buildings
Animals
People
Plants
BBC Bitesize – adaptations

12. Wet environments: monsoon
What are the impacts of a monsoon?
Bangladesh and the positive impacts of a monsoon
When describing impacts don’t forget to develop the knock-on effects e.g. floods > schools are closed > education suffers.
How do people cope with the monsoon rains?
Adapting homes in Bangladesh

13. Dry environments: desert
Deserts have very little rainfall but can be either hot or cold.
How to read a climate graph

14. Energy Revision
Use this PowerPoint in addition to your exercise book to help you revise.

15. What you need to know Types of energy (non-renewable & renewable)

17. Carbon footprints
Carbon footprint is the sum of all the greenhouse gases (e.g. carbon dioxide)that are created by a person, company, event or product.
Make sure you know what they are and why we need to reduce our footprints

18. Acid rain
You need to be able to explain the causes, impacts and responses.
