How Much Do You Know About Volcanoes & Earthquakes?

volcanoes and earthquakes

Posted on
  1. What are Earthquakes?

    movements in Earth's crust
    seismic waves
    my house just kinda shakes idrk
    epicenter
  2. Where do Earthquakes happen?

    along edges of tectonic plate boundaries
    middle of tectonic plate because of buckling
    the ocean
    along edges of tectonic plate boundaries & middle of tectonic plate because of buckling
  3. What are the three types of faults?

    P waves, S waves, L waves
    transform, convergent, divergent
    strike-slip, reverse, normal
    blocks, bombs, lapilli
  4. What type of boundaries do Earthquakes occur at?

    strike-slip, reverse, normal
    transform, convergent, divergent
    P waves, S waves, L waves
    blocks, bombs, lapilli
  5. What are S waves?

    causes compression and contraction, can move through solids liquids and gases
    moves rock side to side, travels through gases and solids, can't travel through liquids
    most destructive, also called L waves, last to arrive at seismograph, can be visible
  6. What are P waves?

    causes compression and contraction, can move through solids liquids and gases
    moves rock side to side, travels through gases and solids, can't travel through liquids
    most destructive, also called L waves, last to arrive at seismograph, can be visible
  7. What are surface waves?

    causes compression and contraction, can move through solids liquids and gases
    moves rock side to side, travels through gases and solids, can't travel through liquids
    most destructive, also called L waves, last to arrive at seismograph, can be visible
  8. Pick the correct answer.

    seismograph- instrument; seismogram- record created by seismograph
    seismogram- instrument; seismograph- record created by seismogram
  9. What do seismograms tell us about earthquakes?

    intensity
    end time
    start time and epicenter location
    intensity and epicenter location
  10. Pick the correct answer.

    epicenter- point inside Earth where Earthquake begins; focus- point on Earth's surface directly above Earthquake's starting point
    epicenter- point on Earth's surface directly above Earthquake's starting point; focus point inside Earth where Earthquake begins
  11. Pick the correct answer.

    Richter scale- numerals I to XII, effects vary from place to place, highest near epicenter; Modified Mercalli Intensity Scale- measures an Earthquake's strength, 10x larger per one increased unit
    Richter scale- measures an Earthquake's strength, 10x larger per one increased unit; Modified Mercalli Intensity Scale- numerals I to XII, effects vary from place to place, highest near epicenter
  12. What's a volcano?

    lava eruption
    aareas of Earth's surface through which magma and gases pass
    clouds of hot debris and ash shoot out
    mountain producing lava
  13. Describe a nonexplosive volcanic eruption.

    Rarer type of eruption; produces clouds of hot debris, ash, and gas; no lava flow; ash remains in atmosphere
    Most common type; produces calm lava flows; occasional lava fountain if enough pressure is present
  14. Describe an explosive volcanic eruption.

    Rarer type of eruption; produces clouds of hot debris, ash, and gas; no lava flow; ash remains in atmosphere
    Most common type; produces calm lava flows; occasional lava fountain if enough pressure is present
  15. What's a volcanic vent?

    body of molten rock deep underground that feeds a volcano
    tube through which magma travels from magma chamber to surface
    magma rises from chamber and spews onto surface
  16. What's a magma chamber?

    body of molten rock deep underground that feeds a volcano
    tube through which magma travels from magma chamber to surface
    magma rises from chamber and spews onto surface
  17. What's a conduit?

    body of molten rock deep underground that feeds a volcano
    tube through which magma travels from magma chamber to surface
    magma rises from chamber and spews onto surface
  18. What is lava?

    liquid magma flows from vent to surface; associated with non-explosive
    forms when magma is blasted into air and hardens; associated with explosive
  19. What is pyroclastic material?

    forms when magma is blasted into air and hardens; associated with explosive
    liquid magma flows from vent to surface; associated with non-explosive
  20. What's viscosity?

    density of lava
    type of lava
    how lava flows
  21. Which are the types of high viscosity lava?

    block & pahoehoe
    aa & pillow
    block & aa
  22. Which are the types of low viscosity lava?

    block & pahoehoe
    aa & pillow
    block & aa
  23. List the order of pyroclastic material from largest to smallest.

    lapilli, ash, blocks, bombs
    ash, lapilli, blocks, bombs
    bombs, blocks, ash, lapilli
    blocks, bombs, lapilli, ash
  24. Which are types of volcanoes?

    shield, cinder cone, composite
    craters, calderas, lava plateaus
    shield, calderas, composite
    cindercone, craters, shield
  25. Which is NOT a way of predicting volcanic eruptions?

    earthquakes
    lava seeps out of fissures
    sides of volcano bulge
    unusually high ground temperature
