Plate Tectonics (Pre-Test)

You were provided with data showing the arrival time of P and S waves recorded from three seismic stations. Which of this can you possibly determine?

• the damage at the focus

• the distance to the earthquake

• the intensity of the earthquake

• the location of the epicenter

From the seismogram, the distance to the epicenter can be determined by measuring

• the speed of the surface waves

• the arrival time of the surface waves

• the ratio of the amplitude of the largest P and S waves

• The difference in the arrival time of the P and S waves

When two tectonic plates collide the oceanic crust usually subducts beneath the continental crust because it is

• denser than continental crust

• less dense than continental crust

• thicker than continental crust

• thinner than continental crust

• rift valley

• trench

Crustal Plate A is moving away from Crustal Plate B. What is the expected average rate of change in position between A and B?

• a few meters per month

• a few millimeters per day

• a few centimeters per year

• a few millimeters per century

Which plate boundary is formed between the Philippine Plate and the Eurasian Plate?

• convergent

• divergent

• reverse fault

• transform fault

Which of these is false about crustal plates?

• have the same thickness everywhere

• include the crust and upper mantle

• thickest in the mountain region

• vary in thickness

Which of these is NOT true about the Philippine Islands?

• most are part of the Philippine Mobile Belt except for Palawan, Mindoro, and Zamboanga

• Formed because of the convergence of the Pacific Plate and the Philippine Plate

• originated geologically in an oceanic-oceanic convergence

• some are parts of the subduction process
