1Oceanic crust is denser yet thinner and mainly made up of basalt
- ATrue
- BFalse
2Continental crust is constantly being destroyed and re-created
- ATrue
- BFalse
3Plates are pushed towards each other. The denser [blank_start]oceanic[blank_end] plate gets forced to [blank_start]subduct[blank_end] under the [blank_start]continental[blank_end] plate. Energy builds up in the subduction zone due to [blank_start]friction[blank_end]. This is sometimes released as an [blank_start]earthquake[blank_end]. As it continues to subduct, the friction also leads to partial melting. The molten rock rises up through [blank_start]fissures[blank_end] until it reaches the surface.
- Aoceanic
- Bsubduct
- Ccontinental
- Dfriction
- Eearthquake
- Ffissures
4When the plates move apart, this boundary is called...
- AConstructive
- BConservative
- CDestructive
5Annotate the formation of fold mountIns
- Arivers carry sediment to geosynclines
- Bsediment lithifies as the plates converge
- Csediment forced upwards into folds
6Ocean trenches are deep sections of the ocean, such as the Challenger Deep, usually found where an oceanic plate is subducting below a continental plate
- ATrue
- BFalse
7How are the Andes used?
- AFarming in Bolivia, using terraces and llamas
- BMining in Peru, such as the Yanacocha Gold Mine
- CHydroelectric power - 47 micro-hydro power stations
- DLlama farms for burgers
- ETourism, like 45km Inca Trail
8How do composite volcanoes vary from shield volcanoes?
- AShield volcanoes are formed at hotspots or constructive plate boundaries
- BComposite volcanoes erupt more frequently
- CShield volcanoes are huge in width, whereas composite volcanoes are tall and steep
- DComposite volcanoes emit low silica lava, making it less viscous
9When did Mt St Helens erupt?
- AMay 18th 1972
- BMay 18th 1980
- CMarch 20th 1980
10Which facts about Mt St Helens are correct?

11Primary effects of Mt St Helens were [blank_start]57[blank_end] people died, an earthquake [blank_start]5.1[blank_end] on the Richter scale, every tree in a [blank_start]250km[blank_end] square area was destroyed and a landslide that blocked 14 miles of the [blank_start]Toutle[blank_end] River. Secondary effects included lahars that destroyed [blank_start]200[blank_end] homes, sediment deposited on river beds and better tourism - [blank_start]3 million [blank_end]visitors each year.

12What would the likely effects of Yellowstone erupting?
- A1 in every 3 people within 1000km of the eruption will be killed
- BLarge ash cloud would rise up to 10km into the atmosphere
- CThe U.K. would see the arrival of ash 10 days after the eruption
- DAsh will cause 'volcanic winter' - temperatures could fall by 10-15 degrees
- E40% of global population could face starvation
13Seismic waves are generated by an earthquake. [blank_start]Primary[blank_end] waves are felt first - they are relatively weak but warn us of the worst to come. [blank_start]Secondary[blank_end] waves are stronger and travel at right angles to the direction of the wave. [blank_start]Surface[blank_end] waves are the final waves. There are two types: [blank_start]longitudinal[blank_end] and [blank_start]transverse[blank_end] (which cause most damage)
- APrimary
- BSecondary
- CSurface
- Dlongitudinal
- Etransverse
14What is the Richter scale?
- ALogarithmic scale for measuring earthquakes, with a 10 fold increase in power every time the scale increases by 1
- BMeasures the effects of earthquakes, based on people's subjective descriptions
15What are the three p's to reduce the impact of earthquakes?
- APredict, protect, prepare
- BPrepare, plan, protect
- CProject, practicalities, protect
16How do people predict earthquakes?
- AEarth tremors, like using seismographs
- BLaser systems that can detect a movement of just 1mm
- CAnimal behaviour, like rats and snakes crawling out of their holes
17The [blank_start]Transamerica[blank_end] Pyramid, San Francisco, was constructed of steel, reinforced concrete and glass. It successfully withstood the [blank_start]1989[blank_end] Lona Prieta earthquake. It swayed 12 inches due to the [blank_start]rubber shock absorbers[blank_end] and interlocking steel frames. To reduce this movement, there are computer controlled weights.
- ATransamerica
- BTrans-siberian
- C1989
- D1975
- Erubber shock absorbers
- Fmetal absorbers
18During Japan's annual '[blank_start]shake out[blank_end]' on the 1st [blank_start]September[blank_end] (the anniversary of the Great Kanto earthquake that killed [blank_start]140,000[blank_end] people), they learn all sorts of things. For example, they learn how to use [blank_start]fire extinguishers[blank_end], to duck cover and hold and even how to perform [blank_start]first aid[blank_end].

Long term responses included an [blank_start]official investigation[blank_end] into why buildings collapsed and, afterwards, building regulations were strictly enforced. Overall, [blank_start]1 billion[blank_end] was poured into L'Aquila.

24There were many effects of the [blank_start]2010[blank_end] Haiti earthquake. Some primary effects included [blank_start]250,000[blank_end] people dead, many by the [blank_start]50[blank_end]% of buildings that collapsed. Such buildings included the [blank_start]Parliament[blank_end] building and the police HQ. Secondary effects included [blank_start]1.5 million [blank_end]homeless and, effectively, no law and order.

- B250,000
- C50
- DParliament
- E1.5 million

25The [blank_start]7.3[blank_end] magnitude earthquake of Haiti had many responses. Immediate responses included [blank_start]16,000[blank_end] UN troops sent to restore law and order.

Long term cake included the '[blank_start]Haiti Fund[blank_end]' - a [blank_start]$11.5 billio[blank_end]n reconstruction package, especially in [blank_start]Karai[blank_end]. These reconstructions will be built to '[blank_start]Life Safe[blank_end]' building codes.
