  • How are sedimentary rocks formed?
    From eroded material that is compacted and cemented over time.
  • What is seismic risk?
    The risk of damage caused by earthquakes and vibrations in the Earth's crust.
  • Which is more dangerous: A volcano in an area with no evacuation plan, or a volcano with good monitoring systems? Why?
    The volcano with no evacuation plan, because people are less protected.
  • What can reduce the impact of volcanic or seismic events? (Name one thing)
    Monitoring, evacuation plans, resistant buildings, dykes.
  • Why is the rock cycle not really a “cycle”?
    Because rocks don’t always go through all the stages or follow a fixed order.
  • What does seismic risk depend on? (Name one factor)
    frequency and violence of earthquakes, or the population at risk.
  • What is a sedimentary rock?
    A rock formed by compacted and cemented sediment.
  • What is a metamorphic rock?
    A rock formed from the transformation of other rocks due to high pressure or temperature.
  • What is an igneous rock?
    A rock formed by the solidification of magma.
  • What type of geological process creates igneous rocks—endogenous or exogenous?
    Endogenouss
  • True or False: Volcanic risk only includes the damage from lava during eruptions.
    False. It also includes gases and indirect effects like earthquakes or tsunamis.
  • What kind of geological processes cause volcanic and seismic risks?
    Endogenous processes
  • True or False: The bigger the population, the lower the geological risk.
    False
  • True or False: Sedimentary rocks are formed deep underground by magma.
    False
  • How are metamorphic rocks formed?
    Through heat and pressure acting on existing rocks.
  • What is geological risk?
    It is the probability of human or material damage in an area as a result of geological processes.
  • The __________ is the continuous transformation of rocks through geological processes
    Rock Cycle
  • True or False: Seismic risk involves the vibrations of the Earth’s surface.
    True
  • How are igneous rocks formed?
    From magma inside the Earth's crust that cools and solidifies.
  • Name one indirect danger caused by a volcanic eruption.
    Earthquakes, tsunamis, or landslides.
