⭐ +315 XP
  • ✓Explain that earthquakes occur on fault lines.
  • ✓Describe how faulting influences landform development.
  • ✓Explain that where the crust is compressed, rocks are folded.
  • ✓State that fold mountains form on convergent plate boundaries.
  • ✓Link boundary processes to hazards and landforms.

When Haiti shook in 2010, buildings collapsed in seconds, but the stress had been building for years along a fault. When Montserrat erupted, the landscape changed, roads, farms and towns were affected by volcanic materials. Both events are ‘messages’ from plate boundaries: the crust bends, breaks, and sometimes melts. In this lesson you’ll learn how faulting and folding shape landforms, and why volcanoes and earthquakes often sit on the same tectonic ‘front lines’.
