What you'll learn

How tectonic and weather hazards form and how people respond.

Tectonic hazards

  • Plates move on convection currents; boundaries are constructive, destructive and conservative.
  • Earthquakes: focus and epicentre; volcanoes: shield vs composite.
  • Effects (primary/secondary) and responses (immediate/long-term).

Weather hazards

  • Tropical storms (cyclones/hurricanes): form over oceans warmer than ~27 °C; structure and the eye.
  • Why they are becoming a bigger risk with climate change.

Reducing risk

  • Monitoring, prediction, protection and planning; why people live in hazardous areas (fertile soil, geothermal energy).

Exam tips

  • Use a named earthquake, volcano and storm case study with figures.
  • Separate primary from secondary effects clearly.

Common mistakes

  • Mixing up constructive and destructive boundaries.
  • Forgetting the reasons people live near hazards.
