Plate Tectonics

It is the location on the Earth's surface directly above the focus of an earthquake

• center

• direct center

• epicenter

• epic center

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

• the arrival time of surface wave

• the difference in the arrival times of the P and S-waves

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

• . the speed of the surface wave

Which theory states that the entire crust is broken and it is continuously moving?

• Continental Drift

• Seafloor Spreading

• Plate Tectonics

• Titanic Theory

What do we call the continuously moving part of the earth’s crust?

• fault

• fissure

• fracture

• plate

A land mass that projects well above its surroundings is a mountain. What do you call a chain of mountains?

• mountain area

• mountain range

• mountain chain

• mountainous

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

• the intensity of the earthquake

• the damage at the focus

• the location of the epicenter

• the distance to the earthquake

It is the largest plate in the lithosphere.

• Eurasian Plate

• North American Plate

• African Plate

• Pacific Plate
