SCIENCE 8 - Q2

• Fault 


  fractures or breaks in Earth.
• Asthenosphere


  also known as the "Upper Mantle."
• Tensional Force


  tectonic force rendered in normal faults.
• Lithosphere


  singular collection of all lithospheric plates
• Crust


  outermost solid layer of the Earth.
• Transform


  type of fault does the violent earthquakes occur.
• Normal


  generally occurs in a place that is relatively high or elevated such as plateau.
• Intensity


  measures the observed effects of an earthquake
• Magnitude


  pertains to the strength and size of an earthquake.
• Causes of Tsunami


  volcanic eruption, earthquake, impact of asteroids.
• Chinese believed that animal behaviors can be used to predict an earthquake.
• Focus


  the point at which energy from the fracturing of interlocking rocks in the lithosphere occur.
• Epicenter


  the area on the crust that is directly above the focus.
• Near the epicenter


  part of the lithosphere where the earthquake magnitude is high.
• Seismologist


  the scientist that study an earthquake.
• Philippines, Canada, and Russia are countries which belong to the earthquake belt.
• San Mateo, Calamba, and Oriental Mindoro are places that belong to the West Valley Fault System.
• MMI Scale


  used in measuring the intensity of an earthquake.
• Richter Scale


  used in measuring the magnitude of an earthquake.
• P-Waves

  1. first to be recorded
  2. they are high frequency seismic waves
  3. also called "primary waves"
  4. a type of body wave
• S-Waves


  also called "secondary waves"
• R-Waves


  exist at any free surface in a continuous body.
• Seismologists can tell the location of the epicenter by measuring the time lag between the arrival of the P- and S-Waves.
• Seismograph


  used to detect, measure, and record seismic waves generated by earthquakes.
• Triangulation


  epicenter of the earthquake where the three circles intersect.
• Two classifications of Seismic Waves: Body Waves and Surface Waves
• Body waves:

  1. P-Waves
  2. S-Waves
• Surface Waves:

  
  

  1. L-Waves
  2. R-Waves
