You were provided with data showing the arrival of P and S waves recorded from three seismic stations. Which of these can you possibly determine?
the damage at the focus
the location of the epicenter
the distance to the earthquake
the intensity of the earthquake
How is the distance to the epicenter measured using the data from the seismogram?
through the speed of the surface waves
through the arrival time of surface waves
through the difference in the arrival times of the P and S-waves
through the ratio of the amplitude of the largest P and S-waves
Why does oceanic crust usually subduct beneath the continental crust when tectonic plates collide?
thicker than continental crust
thinner than continental crust
denser than the continental crust
less dense than the continental crust
Based from the graph above, what is the distance of the epicenter from the seismic station?
900 kilometers
600 kilometers
1800 kilometers
9000 kilometers
If you will visit a place in the pacific known to be a long convergent plate, which of these should you not expect to see?
Rift valleys
Active volcanoes
Volcanic islands
Mountain ranges
3. What causes plates to move?
the movement of water in it
intense heat in the earth’s core
the travelling of P and S waves under it
it is a normal phenomenon without any reason
Where is the epicenter of an earthquake?
Above the surface
It is located at the hypocenter
It is where the damage of the earthquake is focused.
It is located at the point where the earthquake starts to rapture
What safety precautions are you going to do if you are in inside a big building when earthquake strikes?
run for your life
call your mother
run to safety area
duck, cover and Hold
Which of the following describes the epicenter of the earthquake?
It is the point where the P and S waves travel
It is point where the hypocenter is located.
It is a point in the crust where damages happen
It is a point in the crust where a seismic rupture begins.
It is a theory which suggests that Earth’s crust is made up of plates that interact in various ways, thus producing earthquakes, mountains, volcanoes, and other geologic features
The Pangaea Theory
The Theory of Rocks
The Theory of the Earth
The Plate Tectonic theory
How do you describe the earth’s lithosphere?
It is made up of purely part of the crust.
It is made up of purely part of the mantle.
It consists layers, the crust and the lower part of the mantle.
It is made up of layers, the crust and the upper part of the mantle.
How do you describe plate tectonics?
It is the movement of the plates in one direction.
It is the slow movement of the plates in one direction.
It is a lithosphere of the earth that moves slowly but not constantly.
A theory which suggests that earth’s crust is made up of plates that interact in various ways, thus producing earthquakes, mountains, volcanoes and other geologic features.
In what direction does Pacific plate move?
Going to the East
Going to the West
Going to the South
Going to the North
How will you describe the distribution of active volcanoes?
Mostly, volcanoes are found along the edges of some continents and they are not randomly distributed.
Volcanoes are distributed randomly and most of them are found along the edges of the continent.
Mostly, volcanoes are found in the center of the continents.
None of these
Which of these is false about crustal plates?
vary in thickness
thickest in the mountain region
include the crustal and upper mantle
have the same thickness everywhere
