- 1Geological HazardsCaused by tectonic processes
Volcanoes
Earthquakes
Landslides
Avalanches - 2Meteorological hazardscaused by weather and climate
Eg tropical storms
Heatwaves
Blizzards - 3Natural hazardsWhen something is a threat to people or property
- 4CoreThe core is the centre of the earth and is made up of iron
- 5MantleThe mantle is around the core, and is made of semi-molten rock
- 6CrustOuter layer of the earth
- 7Name the 3 types of plate marginsDestructive
Constructive
Conservative - 8What is a plate margin ?Where the plates meet
- 9What is a destructive plate margin ?Where two plates are moving towards each other
When they meet they often Create volcanos and ocean trenches - 10What is a constructive plate margin ?Where two plates are moving away from each other
Then magma fills the gap - 11What is a conservative plate margin ?Where two plates are moving sideways against each other
- 12How is a volcano formed ?1. The plate moves down into the mantle
2. A pool of magma forms
3. Magma rises through the cracks
4. Magma erupts to the surface - 13How are earthquakes formed ?Earthquakes are caused when tension builds up when two plates meet
- 14What is an epicentre?The middle of an earthquake
- 15How are earthquakes measured ?A Richter scale
Or
A Mercalli scale - 16Why do people choose to live near volcanoes ?1. Soil around volcanoes is fertile meaning the can grow crops
2. They are tourist attractions - 17What are the management strategies to reduce a tectonic hazard ?Monitoring
Prediction
Protection
Planning - 18What does eye mean ?The centre of a tropical storm
- 19What is a tropical stormAre areas of intense low pressure with heaving rain and strong winds
- 20Name the 7 different weather hazards in the UKRain
Snow and ice
Hailstorms
Drought
Wind
Thunderstorms
Heatwaves - 21What does climate change mean ?An significant change in the earths climate over a long period
- 22Natural factors that affect climate change ?1. Orbital changes - the way the earth moves around the sun
2. Volcanic activity
3. Solar output - amount of heat the sun gives off - 23Human factors that affect climate change ?1. Burning fossil fuels
2. Cement production
3. Deforestation
4. Farming - 24Environmental effects of climate changeCoastal erosion will increase
Glaciers and ice sheets are melting
Sea levels are rising
