Plate Tectonic Earthquake

According to the diagram, the Ring of Fire is shown by the outline of the —

• Eurasion Plate
• African Plate
• Pacific Plate
• South American Plate

What best describes the process of subduction?

• The process of two places that hold

  land masses colliding causing both plates to shift

  upward forming a mountain range

• The process of more dense plate

  sinking beneath a less dense plate

  during a tectonic collision

• The formation of a fault when two plates meet

  and both plates sink at the same time, creating a chasm between

  them

• The procession of tectonic

  plates pulling away from one another leaving

  cracks between them

What causes an abundant amount of earthquakes to originate around the Japanese islands?

• The islands of Japan is situated on

  top of a large amount of magma.

• The islands of Japan is located on the

  meeting point of several plate boundaries.

• The islands of Japan are unstable volcanic

  landforms that are

  highly active.

• The islands of Japan has a mountainous

  terrain surrounded by water.

According to the diagram, how many major crustal plates exist? 

• 10
• 8
• 7
• 6

Identify the plate boundary. 

• Transform
• Convergent
• Divergent 
• Rift

The mountain shown is composed

of deformed sedimentary layers. They are located near a

tectonic plate boundary and are still increasing in elevation due to—

• seafloor spreading of tectonic plates

• transform faulting of a tectonic plate

• colliding tectonic plates

• subduction of a tectonic plate

Seismic waves generated by an earthquake

at point R are recorded at locations W and X. Which location will receive seismic waves first?

• W

• X

Plate motion occurs as a consequence of convection in the Earth's —

• conduction
• evaporation
• condensation
• convection

Which statement correctly describes the

seismograph reading for locations X and W?

• Location W will experience

  surface waves first.

• Location W and X will not

  experience any surface waves.

• Location W and X will experience

  surface waves at the same time.

• Location X will experience

  surface waves first.

Each dot on the above diagram marks the origin of an earthquake. The area with the  highest concentration of earthquake origins marks—

• a seam of soft rock, such as limestone 
• the location of a developing igneous intrusion 
• the path of the subducting tectonic plate 
• a line of Earth’s magnetic field
