Hazard Management and Plate Tectonics Quiz

What is the definition of a hazard?

• Threat of substantial loss of life, impact on life or damage to property

• A minor inconvenience in daily life

• A type of weather event

• A harmless natural occurrence

Which of the following is NOT one of the three types of hazards?

• Geophysical

• Atmospheric

• Hydrological

• Biological

What is the main focus of the 'Preparedness' stage in the Hazard Management Cycle (PRRM)?

• Raising public awareness of hazards and what to do

• Immediate local/global response

• Restoring normality

• Rebuilding to a better quality of life

Which term describes the process of restoring an area to the same or better quality of life after a hazard?

• Recovery

• Mitigation

• Reconstruction

• Response

What is the main difference between intrusive and extrusive magma cooling?

• Intrusive magma cools below the surface, extrusive cools by air or sea

• Intrusive magma cools by air, extrusive cools below the surface

• Both cool at the same rate

• Both cool only below the surface

Which layer of the Earth is the thickest and mostly molten rock?

• Crust

• Lithosphere

• Mantle

• Core

What is the main cause of plate movement according to the learning material?

• Convection currents in the mantle

• Gravitational sliding only

• Human activity

• Ocean currents

Which of the following best describes a constructive (divergent) plate boundary?

• When two plates separate

• When two plates collide

• When one plate slides past another

• When plates remain stationary

What type of seismic activity is most commonly associated with conservative (transform) plate boundaries?

• Shallow focus earthquakes due to plates sticking and pressure build-up

• Deep focus earthquakes due to subduction

• Volcanic eruptions

• No seismic activity

What is the main feature of oceanic-oceanic destructive (convergent) plate boundaries?

• Formation of island arcs from rising magma

• Creation of rift valleys

• Formation of mid-ocean ridges

• No volcanic activity
