1.2 Tectonic Hazards

• Tectonic hazards are caused by the Earth's mantle

  False
• Tectonic hazards can have devastating impacts on people, infrastructure, and the environment
• Order the three types of convergent plate boundaries:

  1️⃣ Oceanic-Oceanic

  2️⃣ Oceanic-Continental

  3️⃣ Continental-Continental
• Why is understanding plate tectonics important?

  Predict and mitigate hazards
• Example locations for earthquakes include California and Japan
• Convergent boundaries occur where two plates collide
• Divergent boundaries are associated with earthquakes and minor volcanic activity
• Convergent boundaries are associated with earthquakes, volcanoes, tsunamis, and mountain formation
• Earthquakes are caused by the sudden release of energy from plate movement
• What is the primary cause of tectonic hazards?

  Plate movement
• Divergent boundaries only cause minor volcanic activity.

  False
• Match the tectonic region with its associated hazards:

  Ring of Fire ↔️ Earthquakes, volcanic eruptions

  Mid-Atlantic Ridge ↔️ Seafloor spreading, minor earthquakes

  Himalayas ↔️ Earthquakes, mountain formation

  San Andreas Fault ↔️ Severe earthquakes
• Earthquakes are sudden shaking of the Earth's surface caused by the release of energy
• Divergent boundaries result in seafloor spreading and mid-ocean ridges
• Earthquakes result from plates slipping, while volcanoes form from magma rising.

  True
• What process at convergent boundaries may generate tsunamis?

  Subduction
• Match the region with its tectonic plate boundary and associated hazards:

  Ring of Fire ↔️ Convergent (subduction zones), earthquakes, volcanic eruptions

  Mid-Atlantic Ridge ↔️ Divergent, seafloor spreading, minor earthquakes

  Himalayas ↔️ Convergent (collision zone), earthquakes, mountain formation

  San Andreas Fault ↔️ Transform, severe earthquakes
• Match the category of impact with its effects:

  Human ↔️ Loss of life, injuries, displacement

  Environmental ↔️ Landslides, erosion, air pollution

  Economic ↔️ Loss of activities, financial burden
• Steps in responding to tectonic hazards:

  1️⃣ Mitigation

  2️⃣ Preparedness

  3️⃣ Response

  4️⃣ Recovery
• Preparedness for tectonic hazards includes developing emergency plans and conducting drills.
• Implementing comprehensive response strategies can minimize the impacts of tectonic hazards.


  True
• What are tectonic hazards caused by?

  Movement of tectonic plates
• What is the definition of tectonic hazards?

  Natural disasters from plate movement
• What is the theory of plate tectonics?

  Earth's lithosphere is divided
• Convergent boundaries are associated with earthquakes, volcanoes, tsunamis, and mountain formation

  True
• Match the plate boundary with its associated hazards:

  Convergent ↔️ Earthquakes, volcanoes, tsunamis

  Divergent ↔️ Earthquakes, minor volcanic activity

  Transform ↔️ Earthquakes
• What is the definition of earthquakes?

  Sudden shaking of Earth's surface
• Divergent boundaries result in seafloor spreading

  True
• Transform boundaries occur where two plates slide past each other vertically.

  False
• Understanding plate tectonics helps in predicting and mitigating tectonic hazards.


  True
• Match the tectonic hazard with its example location:

  Earthquakes ↔️ California, Japan

  Volcanoes ↔️ Hawaii, Iceland
• At convergent boundaries, the collision of plates can cause earthquakes, volcanoes, and mountain formation
• Order the processes at different plate boundaries based on their effects:

  1️⃣ Collision at convergent boundaries

  2️⃣ Spreading at divergent boundaries

  3️⃣ Sliding at transform boundaries
• A map of tectonic plates and boundaries helps visualize areas prone to tectonic hazards.


  True
• Tsunamis are always caused by earthquakes.

  False
• Volcanoes form from magma rising through cracks in the Earth's crust.


  True
• The primary cause of tectonic hazards is the movement of the Earth's tectonic plates
• Understanding plate boundary processes is essential for predicting and mitigating tectonic hazards.


  True
• What type of plate boundary is associated with seafloor spreading?

  Divergent
• What environmental effect can air pollution from tectonic hazards cause?

  Reduced air quality
