Geography and Natural Hazards Quiz

What are Aseismic Buildings designed to do?

• Withstand or minimize destruction during an earthquake

• Accumulate material at subduction points

• Burn vegetation to reduce wildfire fuel

• Circulate magma within the mantle

What is the Asthenosphere?

• The Earth's crust where seismic energy is released

• The upper mantle layer of the Earth, semi-molten and approximately 2000km wide

• The point on the surface above the earthquake's origin

• The circulation of magma within the mantle

What are Ash particles?

• The Earth's spin affecting air masses

• Fine particles and dust ejected during an eruption

• The movement of tectonic plates

• The sequence of governance of a natural hazard

What is Continental Drift?

• The movement of tectonic plates due to varying weights of crust

• The Earth's spin affecting air masses

• The accumulation of material at the point of subduction

• The sequence of governance of a natural hazard

What are Convection Currents?

• The Earth's spin affecting air masses

• The circulation of magma within the mantle

• The movement of tectonic plates

• The accumulation of material at the point of subduction

What is the Coriolis Effect?

• The Earth's spin affecting the movement of air masses and winds

• The movement of tectonic plates

• The accumulation of material at the point of subduction

• The sequence of governance of a natural hazard

What is the Epicentre?

• The place in the crust where seismic energy is released

• The point on the surface directly above the earthquake's origin

• The circulation of magma within the mantle

• The Earth's spin affecting air masses

What is Fatalism?

• The belief that hazards are uncontrollable, so losses should be accepted

• The movement of tectonic plates

• The accumulation of material at the point of subduction

• The sequence of governance of a natural hazard

What causes a Jokulhlaup?

• A flow of mud and debris

• A sudden glacial flood caused by a glacier on top of or near a volcano

• A surface earthquake wave

• A measure of an earthquake's energy

What does the Moment Magnitude Scale measure?

• The thickness of the lithosphere

• The energy released during an earthquake

• An earthquake's energy released

• The alternating polarisation of new land
