Measures and records ground motion

• seismogram

• seismologist

• seismic

The shaking of the ground that results breaks in Earth's lithosphere.

• Volcanic eruption

• Fault

• Tsunamis

• Earthquake

The following are types of fault EXCEPT

• strike-slip

• normal

• elevate

• reverse

A break in Earth's lithosphere where one block of rock moves

• earthquake

• fault

• eruption

• tsunamis

What triggers an earthquake? (choose all causes)

• Movement of tectonic plate

• Volcanic eruptions

• Rapid motion along a fault

• Calmness of the ocean

What is the relationship between earthquake and plate boundaries?

• There is no connection between earthquake and plate boundaries

• Earthquake result from the build-up and release of stress along active plate boundaries.

• Earthquake doesn't occur in plate boundaries

• When plate separates there will be no earthquake

The energy release that travels as vibration is called

• light wave

• thermal wave

• seismic wave

• vibration

What do you call where waves originates and rocks first move along the fault?

• fault

• epicenter

• focus

• wave

It is also called a P wave.

• primary wave

• secondary wave

• surface

• seismic

A wave that moves up and down at right angles slower than a P wave

• primary wave

• secondary wave

• surface wave
