Deep ocean trench
Subduction zone
The difference between magma and lava is...
where it is found (above or below the surface)
how hot the molten rock is (lava is hotter than magma)
the type of boundary where it forms
the viscosity of the molten rock (lava has a lower viscosity)
Choose the statements that are hazards associated with volcanoes
Pyroclastic flow
Gases such as carbon dioxide and sulphur dioxide
Mudflow
Hurricanes

Sedimentary
Metamorphic
Igneous
Choose the correct statements.
Ash from an eruption...
can cause earthquakes.
can be heavy enough to make roofs collapse
can ruin crops.
gets everywhere - in your eyes, your hair, your lungs.
Pyroclastic flows....
Travel at 100 km/hour. They sweep everything along. People drown in mud.
Travel at up to 200 km/hour. They scorch and smother everything in their path.
Block out the sun leading to temperatures falling around the world.
Can be avoided by walking out of the way.
Continental and oceanic crust - Choose the correct statements
Continental crust is older than oceanic crust
Continental crust is lighter than oceanic crust
Oceanic crust is thicker than continental crust
Oceanic crust can sink so can be renewed or destroyed
What happens to the oceanic crust at a destructive plate boundary?
It collides (crashes) into the continental plate, forming fold mountains
It rises above the continental plate
It sinks below the continental plate and melts to form magma
Which of the following best describes the FOCUS of an earthquake?
The point on the Earth's surface where the earthquake is felt most strongly
The point under the ground where the earthquake occurs
The join between the two tectonic plates
Which of the following best describes the EPICENTRE of an earthquake?
The point on the Earth's surface where the earthquake is felt most strongly
The point under the ground where the earthquake occurs
The join between the two tectonic plates
Why do the tectonic plates suddenly become unstuck and release all their stored energy?
Water from rainfall soaks into the rock and makes it slippery
The pressure pushing the plates past each other overcomes the friction holding them together
The friction holding the plates together weakens
What is the name for the piece of equipment used to measure earthquakes?
A seismogram
A seismograph
A Richter scale
How many times greater is a magnitude 5 earthquake compared to a magnitude 4 earthquake on the Richter scale?
1 times greater

100 times greater
What is the name for the smaller earthquakes often felt before the main shock of an earthquake?
Preshocks
Priorshocks
Foreshocks
What is the name for a smaller earthquake that occurs after a large earthquake?
Foreshock
Aftershock
Latershock
At a conservative plate boundary, what is happening to the two plates?
They are moving towards each other
They are moving away from each other
They are moving alongside each other
Which of the following is NOT a secondary impact of an earthquake?
People becoming ill due to drinking contaminated water
Fires starting due to damaged gas and electricity supplies
Buildings collapsing

Looting and violence were a major problem in Christchurch
Fires were caused by both earthquakes
The 2011 earthquakes - Haiti v Christchurch.
Which statements about responses are true?
Damage to infrastructure such as roads, ports and airports slowed down aid reaching Haiti
A 6.1 magnitude aftershock weakened buildings and slowed down the recovery effort in Haiti
In both countries, local people used their bare hands to try to free survivors trapped under rubble.
All of the statements are true
The 2011 earthquakes - Haiti v Christchurch.
Which statements about responses are true?
The buildings in Haiti were stronger
The buildings in Christchurch were stronger
The government of Haiti were well prepared for the disaster
The Christchurch fire service coordinated the rescue effort
All of the statements are true
