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
You are an oceanographer and want to map the ocean floor on the east coast of the Philippines. As you do your study, you notice that there is a portion in the ocean floor which is relatively much deeper than the rest. What most likely is the deeper part?
linear sea
oceanic ridge
rift valley
trench
If you will visit a place in the Pacific known to be along converging plates, which of these should you not expect to see?
active volcanoes
mountain ranges
rift valleys
volcanic islands
What do you expect to find at a mid-ocean ridge?
reverse fault
very ancient rock
relatively young rocks
thick accumulation of sediments
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

the Philippines has many islands
there are lots of earthquakes
there are many volcanoes
