What causes tectonic plates to move?
radiation from within the crust
magnetic forces from the inner core
convection currents in the mantle
slow continental drift
When will an earthquake occur?
Air on the ground evaporates along a fault.
Rocks underground suddenly break along a fault.
Soil on the ground was suddenly eroded by a flash flood.
Water underground usually breaks along a fault.
Most earthquakes occur near the ______ of tectonic plates.

boundaries
center
ocean ridges
In what tectonic plate are most of the islands in the Philippines found?
Eurasian plate

Pacific plate
What happens when a continental and oceanic plate move toward each other?
nothing is formed
both plates will be subducted
the continental moves under the oceanic plate
the oceanic is pushed below the continental plate
What do earthquakes, volcanoes, and mountains have in common?
They occur suddenly
They cause major hazards
They are measured using seismographs
They result from plate movement
Seismic waves start at the _______ .
epicenter
focus
seismic distance
seismic gap
Why does the basaltic oceanic crust always subduct beneath the granitic continental crust?
Denser than the continental crust
Less dense than the continental crust
Solid than the continental crust
Shinier than the continental crust
This theory states that Earth's crust and rigid upper mantle are broken into enormous slabs which move in different directions.
tectonic plate theory
seafloor spreading theory
the theory of Pangaea
the floating Earth theory
What starting point is to be traced to locate the epicenter of an earthquake?
First P wave and the first S wave
Second P wave and the second S wave

How are plate tectonics and volcanoes related?
They have nothing to do with one another.
Volcanoes are formed near where plates collide and in the ocean.
Volcanoes are not formed where plates collide, but do form in the oceans.
Volcanoes are formed anywhere else.
When will an earthquake occur?
Air on the ground evaporates along a fault.
