    Study Notes

    Lava Types

    • Viscosity is the resistance of a fluid to flow, and different types of lava have different viscosities.
    • There are three common types of lava: basaltic, andesitic, and rhyolitic.
    • Each type of lava contains different amounts of silica (SiO2) and dissolved gases.

    Faults

    • A fault is where two earth plates meet.
    • There are three main types of fault movements in earthquakes:
      • Normal Fault: plates move apart and the hanging wall moves down.
      • Reverse Fault: plates press together and the hanging wall moves up.
      • Strike-Slip Fault: both plates slide past each other.

    Seismic Waves

    • Seismic waves are the waves of energy caused by an earthquake.
    • There are two main types of body waves:
      • P wave (primary): arrives first, moves with a push-pull motion.
      • S wave (secondary): arrives second, moves with an up and down motion.

    Seismology

    • Seismology is the scientific study of earthquakes.
    • A seismologist is a scientist who studies earthquakes.
    • A seismograph is the scientific instrument that records seismic waves from an earthquake.

    Earthquake Location

    • The focus is where the earthquake slip happens below the ground.
    • The epicenter is where the shaking is first felt above ground, directly above the focus.

    Ring of Fire

    • The Ring of Fire is a major area in the basin of the Pacific Ocean where a large number of earthquakes and volcanic eruptions occur.
