Q.1
Which of the following is NOT a reason why more people might die when a volcano erupts in an LEDC?
  • The ash cloud blots out the sunlight, killing crops and leading to starvation
  • Low literacy skills
  • Not everyone has a radio or TV
  • Poor communications infrastructure
Q.2
What else comes out of a volcano as well as lava?
  • Liquid water
  • Ash and gases
  • Ice particles
  • Fossils
Q.3
What type of magma usually occurs in volcanoes at destructive plate boundaries?
  • Superheated viscosity
  • Ashless viscosity
  • Low viscosity
  • High viscosity
Q.4
What is the name given to magma that flows out of a volcano onto the Earth's crust?
  • Igneous rock
  • River rock
  • High density magma
  • Lava
Q.5
Volcanic eruptions are often seen as being negative, however, they can have some positive effects on an area. Which of the following is NOT a positive effect for a volcanic area?
  • Dramatic scenery can attract tourists
  • Ash from volcanic eruptions near the sea attracts more fish as they feed from the extra nutrients that dissolve into sea water
  • The high level of heat in the ground near to volcanoes can provide the hot water for geothermal energy
  • Certain types of ash and lava break down to provide nutrients for soil
Q.6
What type of magma occurs in volcanoes at constructive plate boundaries?
  • High viscosity magma
  • Superheated magma
  • Low viscosity magma
  • Supercooled magma
Q.7
Where do volcanoes occur?
  • In well defined narrow belts around the world
  • Randomly around the surface of the Earth
  • Only on land
  • On small islands
Q.8
What is a constructive plate boundary?
  • Where plates move apart
  • Where plates move together
  • Where plates move sideways past each other
  • Where the plates are not moving
Q.9
What is a destructive plate boundary?
  • Where one plate is being pushed back down into the mantle
  • Where two plates are moving apart, destroying the area between them
  • Where two plates are moving sideways past each other
  • Where new land is being formed and then eroded quickly by the sea and earthquakes
Q.10
Which of the following is a primary effect of a volcanic eruption?
  • Ash blocking rivers causing crop destruction by flooding
  • Lava flow destroying property
  • Debris carried by rivers damaging bridges
  • Silting up of harbours caused by ash carried away from the area where the eruption happened by rivers
