Hazards Mid Topic Quiz

State which type of earthquake wave travels fastest.

Which of the following is a secondary hazard caused by an earthquake?

• Tsunami due to water displacement

• Ground shaking

• Earthquake epicenter

• Seismic waves

Plate tectonic theory is used to explain plate movements. Which of the following best describes this theory?

• The Earth's crust is divided into large plates that float on the semi-fluid asthenosphere beneath them.

• The Earth's surface is a single solid shell that does not move.

• The Earth's crust is made up of small, immovable pieces.

• The Earth's surface is constantly shrinking and expanding.

Where are most volcanic eruptions found?

• Volcanic eruptions are evenly distributed across the globe.

• Volcanic eruptions are concentrated along tectonic plate boundaries.

• Volcanic eruptions occur only in the Northern Hemisphere.

• Volcanic eruptions are random and unpredictable.

Why do some tectonic hazards occur away from plate boundaries?

• Due to mantle plumes and hotspots

• Because of oceanic trench formation

• As a result of subduction zones

• Due to transform fault boundaries

Which of the following are parts of the Pressure/Release Model?

• Root causes

• Dynamic pressures

• Unsafe conditions

• All of the above

What is the primary cause of tectonic plate movement?

• Wind and ocean currents

• Convection currents in the mantle

• Magnetic fields of the Earth

• Gravitational pull from the moon

Which of the following is a characteristic of a convergent plate boundary?

• Plates move towards each other

• Plates move away from each other

• Plates remain stationary

• Plates slide past each other

What is a common effect of volcanic eruptions on the atmosphere?

• Decrease in carbon dioxide levels

• Formation of new tectonic plates

• Increase in oxygen levels

• Release of ash and gases

What is the primary effect of tectonic plate divergence?

• Subduction of one plate under another

• Creation of new oceanic crust

• Formation of mountain ranges

• Formation of deep ocean trenches
