What is a constructive plate boundary?
Convection currents in the mantle move the plates away from one another, not smooth, magma rises from under oceanic crust to form underwater volcanoes which grow into volcanic islands - Iceland.
1 of 22
What is a destructive plate boundary?
Convection currents in the mantle cause plates to move together where there is different types of crust - oceanic and continental. Oceanic - more dense, is subducted and causes friction. Heat from the mantle melts the oceanic crust into magma.
2 of 22
What is a conservative plate boundary?
Convection currents in the mantle cause plates to slide past one another at different speeds that can lead the plates to become locked together as of friction.

Primary effects of The Haiti earthquake 12th January 2010?
Shaking, Houses destroyed, death, injury, electricity supplies disrupted, roads blocked, airport unusable.

Secondary effects of the Haiti earthquake 12th January 2010?

Primary effects of the 2011 Christchurch earthquake?
181 people killed, 2,000 people injured, loss of electricity, airport closed, water and sewage pipes damaged, 50% of central city buildings damaged, liquefaction cause damage to roads and buildings.

Describe composite volcanoes...
Destructive boundary, strato volcanoes, pacific ring of fire, vicious lava, gassy, Mt St Helen's, cone shaped, tall, explosive, acid lava.
9 of 22
Describe shield volcanoes...
Basic lava, gentle eruptions, hotspots - Hawaii, very little ash, non-viscous lava, constructive boundaries, gentle slopes.
10 of 22
Ways a volcano can be monitored:
Restricting access to the area, evacuating the area, reducing the effects of the eruption.
11 of 22
Why do people live in hazardous areas?
Geothermal power - gives people free hot water, low cost, renewable, boosts tourist industry - Iceland. Mineral extraction - now have become tourist attractions. Agriculture - melting ice to give fertile soil. Tourism - blue lagoon, geysers.

Where do tropical storms form?
Over sea - not land, between 10 degrees north and 30 degrees south of the equator. Sea temp. 26 degrees and at depths 60m. Not on equator as of corollas force.

Managing tropical storms in Bangladesh...
Shelter built on concrete pillars, windows have no glass and are covered with bars and metal shutters, stairs are located at the back of the building with railings to hold on to, the building is a triangular shape.
14 of 22
Reducing the damage from tropical storms in Bangladesh...
Charities are helping to build cyclone shelters, helping local people to build houses on stilts, educating women of the importance of cyclone shelters, tree planting along the coast, Met office in Dhaka, Satellite monitoring systems, warning helpers.
15 of 22
Reducing the damage from tropical storms in USA...
Preparing the community - hurricane preparedness week, practise days, emergency kits, May 24th to 31st, strict building regulations & land use planning, hurricane proof buildings, FEMA - carries out evacuation, coordinates police etc.

Primary impacts of wildfires?
Destruction of property, loss of life, injury, health problems for people, burning of vegetation and crops, water and air pollution.
21 of 22
Secondary impacts of wildfires?
Tourism - attractive landscapes can be destroyed, insurance payments, push up the insurance costs for others, can increase risk of soil erosion and landslides, homelessness, effects on ecosystem, loss of jobs and income.
