- Inner Core
- Outer Core
- Mantle
- Crust
- Continental
- Oceanic
- Distribution
- The Earth's crust is broken up into pieces
- Heat rising & falling creates a convection current
- Moves the plates
- Converge= Toward each other
- Diverge= Move apart
- Plate Tectonics
- Cause earthquakes & volcanoes
- The part where two plates meet is a plate boundary
- Constructive= move apart
- Destructive= move toward
- Conservative= slide past
- The part where two plates meet is a plate boundary
- Cause earthquakes & volcanoes
- Moves the plates
- Four concentric layers
- Climatic Hazards
- Droughts
- Not enough rainfall to supply people or crops.
- Huiman causes
- Over population, Deforestation
- Over extraction, Politics
- Natural causes
- Weather
- El Nino
- Global warming
- Desertification
- Occurs where land is turned into desert.
- Human Impacts
- Crops & cattle die- famine
- Death
- Migrants move to cities
- Informal settlements
- Shanties
- Already over-populated
- Physical Impacts
- Flash floods, Cracked Soil, Loss of plants & animals
- Soil erosion, Gullying, Dry Rivers
- Growth of desert & Sand storms
- Droughts
- Aid
- Types
- Long-term
- Advanntage: Sustainable development
- Involves providing local communities with education & skills
- Emergency
- Advantage: Saves lives in times of disaster
- Dis- advantage: Can increase dependancy
- Needed for sudden disasters
- Tied
- One country donates to another with conditions
- Dis- advantage: Usually benefits the MEDC only
- Multilateral
- Given through international organisations
- Dis-advantage: can be very Top-down
- Long-term
