The Challenge of Natural Hazards (AQA GCSE)

What is the outermost layer of the Earth called?

• The Mantle

• The Crust

• The Core

• The Asthenosphere

Which process causes tectonic plates to move?

• Earthquake waves

• Convection currents, slab pull, and ridge push

• Volcanic eruptions

• Ocean currents

What is a lahar?

• A fast-moving current of super-heated gas and ash

• A thick lava fragment ejected from a volcano

• A volcanic mudflow which usually runs down a valley side on the volcano

• A cloud of pulverised rock and glass

Which of the following is NOT a method used to predict earthquakes?

• Satellite surveying

• Seismometer

• Water table level

• Gas sampling

What is the point directly above the focus of an earthquake called?

• Epicentre

• Seismic wave

• Fault line

• Crust

Which of the following is a method to protect against earthquake damage?

• Building earthquake-resistant buildings

• Increasing volcanic activity

• Lowering water table levels

• Creating exclusion zones

What is a natural hazard?

• A man-made event causing damage

• A natural process which could cause death, injury or disruption to humans, property and possessions

• A weather forecast

• A type of tectonic plate

What causes earthquakes at plate boundaries?

• Plates moving apart and creating new crust

• Plates locking and friction building up until released

• Plates melting and forming magma

• Plates cooling and becoming denser

Which types of plate margin is responsible for devastating earthquakes?

• Constructive plate margin

• Destructive plate margin

• Conservative plate margin

• Passive plate margin

What is the main difference between geological and meteorological hazards?

• Geological hazards are caused by weather, meteorological by tectonic processes

• Geological hazards are caused by land and tectonic processes, meteorological by weather and climate

• Meteorological hazards are always more dangerous

• Geological hazards only occur in the ocean
