1.2 Tectonic Hazards

• Tectonic hazards are caused by the movement of the Earth's plates
• Earthquakes occur due to the sudden movement of plates
• What is the major volcanic region in the world?

  Pacific Ring of Fire
• Match the tectonic hazard with its primary geographic distribution:

  Earthquakes ↔️ Convergent and transform boundaries

  Volcanic Eruptions ↔️ Convergent plate boundaries

  Tsunamis ↔️ Coastal regions near convergent boundaries

  Landslides ↔️ Mountainous regions near plate boundaries
• Landslides are often triggered by earthquakes or heavy rainfall
• Earthquakes and tsunamis can lead to widespread death and homelessness.


  True
• What is the primary cause of tectonic hazards?

  Plate movement
• Landslides involve the downslope movement of soil and rock.

  True
• What drives the movement of tectonic plates?

  Mantle convection
• Which plate boundary is associated with the formation of the Mid-Atlantic Ridge?

  Divergent
• Tsunamis are often caused by underwater earthquakes.


  True
• Match the tectonic hazard with its geographic distribution:

  Earthquakes ↔️ Pacific Ring of Fire

  Volcanic Eruptions ↔️ Convergent plate boundaries

  Tsunamis ↔️ Coasts near underwater earthquakes
• Why is understanding the geographic distribution of tectonic hazards important?

  Mitigating risks
• Earthquakes can disrupt businesses and transportation
• Volcanic eruptions can pollute the atmosphere.


  True
• Community engagement and education are essential for preparing for and responding to tectonic hazards
• Match the type of tectonic hazard with its effect:

  Volcanic Eruptions ↔️ Ash clouds

  Tsunamis ↔️ Coastal inundation

  Landslides ↔️ Mudflows
• Plate boundaries can be convergent, divergent, or transform.


  True
• What geographic feature is most closely linked to the distribution of tectonic hazards?

  Plate boundaries
• What type of plate boundary typically generates tsunamis?

  Convergent
• What is an example of an economic impact caused by earthquakes?

  Disruption of transportation
• Match the type of impact with a key example:

  Economic ↔️ Destruction of crops by volcanic eruptions

  Social ↔️ Widespread death from tsunamis

  Environmental ↔️ Pollution of air by volcanic ash
• Order the sequence of events that lead to a tsunami:

  1️⃣ Underwater earthquake

  2️⃣ Generation of large waves

  3️⃣ Coastal flooding
• Plate boundaries are major zones for earthquakes and volcanic eruptions
• What is the primary factor influencing the geographic distribution of tectonic hazards?

  Plate boundaries
• Landslides near plate boundaries are often triggered by earthquakes or heavy rainfall
• Match the impact type with a key example:

  Economic ↔️ Damage to infrastructure

  Social ↔️ Displacement of populations

  Environmental ↔️ Destruction of natural habitats
• What social impact can earthquakes and tsunamis cause?

  Death and homelessness
• Match the tectonic hazard with a preparedness measure:

  Earthquakes ↔️ Emergency supplies

  Volcanic Eruptions ↔️ Evacuation procedures

  Tsunamis ↔️ Coastal defenses

  Landslides ↔️ Slope stabilization
• Tectonic hazards pose risks to humans and the environment.


  True
• Order the processes that cause tectonic hazards:

  1️⃣ Plate Boundaries interaction

  2️⃣ Mantle Convection currents

  3️⃣ Fault Zones strain accumulation
• Tsunamis are typically generated by underwater earthquakes
• The Pacific Ring of Fire is a major zone for both earthquakes and volcanic eruptions.


  True
• Order the categories of impacts from tectonic hazards based on their primary focus:

  1️⃣ Economic

  2️⃣ Social

  3️⃣ Environmental
• Volcanic eruptions can pollute the atmosphere and contaminate ecosystems
• Volcanic eruptions release magma, ash clouds, and pyroclastic flows
• Which country experienced the devastating Tōhoku earthquake and tsunami in 2011?

  Japan
• Fault zones are areas where fractures in the Earth's crust accumulate strain.


  True
• What type of plate boundary typically generates tsunamis?

  Convergent
• Vulnerable coastal regions for tsunamis include the Pacific Ocean, Indian Ocean, and Mediterranean
