  • What is a constructive plate boundary?
    A boundary where two tectonic plates move apart.
  • Example of a constructive plate boundary?
    The Mid Atlantic Ridge.
  • What are the volcanoes and earthquakes like at a constructive plate boundary?
    There's shield volcanoes and gentle earthquakes
  • What is a conservative plate boundary?
    Two plates move side by side they get stuck and then there's a sudden jolt
  • What is a destructive plate boundary?
    The more dense oceanic crust is subducted beneath the continental crust, pressure builds and when it releases there's an earthquake. Alternatively a magma chamber is formed and this forms a volcano.
  • What are the earthquakes and volcanoes at a destructive plate boundary like?
    Dangerous
  • What are collision boundaries?
    Two boundaries of the same type collide
  • What forms at collision boundaries?
    Fold mountains and earthquakes
  • How are earthquakes measured?
    Seismometers
  • How are volcanoes measured?
    Satellite imaging for shape and thermal imaging for temperature and spectrometer for gas emissions
  • How to mitigate a volcanoes effects?
    An exclusion zones and strong communication system
  • How to mitigate an earthquakes effects?
    Steel frames, shatter proof glass, numbers painted on city roofs to speed up rescue attempts
