Understanding Hazardous Environments Part 1

What are hazardous environments?

• Places where only non-toxic materials are used.

• Hazardous environments are settings that pose risks to health and safety due to dangerous substances or conditions.

• Environments that are always safe and secure.

• Settings that have no impact on health or safety.

Why is it important to understand tectonic processes?

• Tectonic processes have no impact on climate change.

• Tectonic processes are only relevant to geology students.

• Understanding tectonic processes is unnecessary for urban planning.

• It is important to understand tectonic processes to predict natural disasters and manage resources effectively.

What is the lithosphere?

• The lithosphere is the rigid outer layer of the Earth, including the crust and upper mantle.

• The lithosphere is the atmosphere surrounding the Earth.

• The lithosphere is the Earth's core made of molten metal.

• The lithosphere is the liquid layer of the Earth beneath the crust.

What drives the movement of tectonic plates?

• Convection currents in the Earth's mantle.

• Magnetic field fluctuations

• Gravitational pull from the moon

• Earth's rotation

What occurs at divergent boundaries?

• New crust is formed as tectonic plates move apart.

• Crust is destroyed as tectonic plates collide.

• Volcanic eruptions occur due to plate subduction.

• Earthquakes are caused by plates sliding past each other.

What happens at convergent boundaries?

• Tectonic plates slide past each other without interaction.

• Tectonic plates remain stationary, causing no geological activity.

• Tectonic plates collide, causing subduction, mountain formation, earthquakes, and volcanic activity.

• Tectonic plates move apart, creating new oceanic crust.

What is subduction?

• A method of measuring tectonic plate movement.

• The process of two tectonic plates colliding and pushing upwards.

• The formation of new tectonic plates from magma.

• Subduction is the process of one tectonic plate being forced beneath another.

What are transform boundaries?

• Transform boundaries are where tectonic plates collide and create mountains.

• Transform boundaries are regions where tectonic plates move apart from each other.

• Transform boundaries are areas where tectonic plates sink into the mantle.

• Transform boundaries are locations where tectonic plates slide past each other horizontally.

How do earthquakes relate to tectonic processes?

• Earthquakes are solely caused by volcanic activity.

• Earthquakes occur randomly without any geological cause.

• Tectonic processes have no impact on seismic activity.

• Earthquakes are caused by the movement of tectonic plates and the release of stress along faults.

What are volcanic hazards?

• Landslides and rockfalls

• Earthquakes and tsunamis

• Volcanic hazards include lava flows, ash fall, pyroclastic flows, volcanic gases, and lahars.

• Flooding and droughts
