Use this PowerPoint in conjunction with your books to help you revise. Year 7 Test Revision Use this PowerPoint in conjunction with your books to help you revise.

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

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

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) Kung Fu plate Boundaries video

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.

Mt St Helens Mt St Helen’s song

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

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

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

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

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

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

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

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

What you need to know Types of energy (non-renewable & renewable) Carbon footprints Acid rain: causes, effects and responses Global warming: causes, effects and responses

Types of energy Non-renewable Renewable Oil Coal Gas Nuclear Wood Non-renewable energy sources Solar Wind Wave Tidal Geothermal Biomass Renewable energy sources

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 Carbon footprint revision website

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

Global Warming You need to know the causes, impacts and responses. Global Warming - None like it hot! Greenhouse Effect explanation
