Vulcanicity – Review and assessment

By the end of the lesson, the learner should be able to:

- Explain how tectonic plate movements at different boundaries influence the type and intensity of volcanic activity
- Compare intrusive and extrusive volcanic features in terms of formation and impact on the landscape
- Relate the global distribution of volcanic features to human settlement, economic activities and disaster preparedness in different regions

- Answer review questions on causes, features, distribution and significance of vulcanicity
- Compare intrusive and extrusive features using a summary table
- Present and discuss answers in class for consolidation and peer review

How does the global distribution of volcanic features influence where people choose to live and how they earn a living?

Earthquakes – Meaning and types of earthquakes
Earthquakes – Causes of tectonic and volcanic earthquakes

By the end of the lesson, the learner should be able to:

- Define the term earthquake and identify the main types: tectonic, volcanic and artificially induced earthquakes
- Describe the causes of each type of earthquake
- Relate earthquake events such as the San Andreas Fault tremors to the importance of earthquake-resistant building designs and early warning systems in urban areas

- Brainstorm on the meaning, types and causes of earthquakes in the world and share in class
- Use approved Geography reference books or digital devices to research the meaning of each earthquake type
- Write summary notes and present in class for peer review

Earthquakes – Artificially induced earthquakes

By the end of the lesson, the learner should be able to:

- Explain how human activities including fluid injection, underground nuclear explosions, mining and reservoir filling can cause earthquakes
- Discuss the relationship between human activities and increased seismic risk in affected areas
- Relate induced seismicity from mining operations in Kenya to the need for responsible extraction practices that protect surrounding communities

- Study photographs of mining explosions and discuss the causes of artificially induced earthquakes
- Discuss how fluid injection, nuclear explosions, mining and reservoir filling trigger seismic activity
- Write summary notes and present in class

How can human activities that change the stress balance in the Earth's crust trigger earthquakes?

Earthquakes – Distribution of earthquake zones

By the end of the lesson, the learner should be able to:

- Identify the major earthquake zones in the world including the Pacific Ring of Fire, Mid-Atlantic Ridge and transform fault zones
- Draw a world map showing the distribution of earthquake zones and label key regions
- Relate the distribution of earthquake zones to tectonic plate boundaries and use this knowledge to identify high-risk regions for disaster planning

- Study maps showing the distribution of earthquake zones and identify areas affected by convergent, divergent and transform plate movements
- Sketch a world map showing earthquake zone distribution on manila paper
- List countries most frequently affected by earthquakes and present findings in class

Why are some countries more frequently affected by earthquakes than others?

Earthquakes – Effects of earthquakes on the environment
Earthquakes – Measurement of earthquakes

By the end of the lesson, the learner should be able to:

- Investigate the primary and secondary effects of earthquakes on the environment including ground collapse, tsunamis, landslides and fires
- Describe how earthquakes affect buildings, infrastructure and water sources
- Relate the devastating effects of earthquakes such as tsunamis and building collapses to the need for earthquake-resistant infrastructure and community preparedness in Kenya

- Study pictures showing the impact of earthquakes on the environment and discuss effects observed
- Use digital resources or reference materials to search for effects of earthquakes on the environment
- Watch video clips on effects of earthquakes and write summary notes

How do the secondary effects of an earthquake such as tsunamis and fires often cause more damage than the earthquake itself?

Earthquakes – Disaster preparedness and management

By the end of the lesson, the learner should be able to:

- Design disaster preparedness and management strategies for coping with effects of earthquakes
- Describe prevention, preparedness, response and recovery measures for earthquake disasters
- Relate earthquake preparedness strategies to real-life community actions such as evacuation drills, early warning systems and reinforced building standards used in earthquake-prone countries like Japan

- Suggest ways to prepare for and manage the effects of an earthquake and write notes as a group
- Listen to a resource person on disaster preparedness and management strategies for earthquakes
- Design communication messages on safety precautions for earthquake preparedness and display on school noticeboards
